Do you also feel interested in programming? From Oops concepts, from keywords, from identification
concepts, now what is Dart programming? Dart programming is a mixture of Java and JavaScript, after
learning which you can easily start development in Flutter. If not, you can take your skills to a higher level,
but that will happen only when you know the basics to advanced concepts of Dart. So, in this particular
series, we will see all those things that are needed for an app developer or an app developer.
If it is a matter of interest for a developer then in this particular series you will be told about OOPs
concept, you will be told about generics, you will be told about packages, apart from this, MAPESTRINGER
and all these things will be cleared in depth. So let's go in this series in which we are going to see
about Hands-On Programming and step by step we will clear all those programming concepts. If you
also want to start your career in fast development and want to get a good high package job then WCaptech
is for all of you.
Here comes a fully practical Flutter Pup development course in which you will get live interact classes,
doubt sessions, assignments, tests, cheat sheets and all these things. You will get these Flutter Pup
development codes just by calling on the given number or book your free demo classes by filling the form
given in the description. So let's go in this series in which we will clear the basic to advanced concepts of
DIT [Prashasa] [Music] About DIT installation, how can we install DIT on our Windows system, so let's
go directly in the browser
And to install the SDK of the hand and by visiting the official website of the hand you can download the SDK
in a simple way, after opening the simple page you have to scroll down and here I am telling you important
these commands require administrative rights, so here we have some commands with the help of which we
can easily execute the command as well as we can download the SDK which is for hand, for this you have
to tap on the downloaded SDK as a zip file and after tapping open the simple page, what you have to
do here is download it
you have to select and dot adk a 256 you have to select this particular file here after selecting and you
have to click on the menu here downloading of this has started here so as soon as the downloading is
completed after that we will setup it within the environmental variable the zip of our SD has been downloaded
here so first of all we will unzip this particular zip file and after unzipping we will set its path within the
environmental variable so first of all you have to
First you have to open the file explorer here and after opening it you have to go to the download section
and first of all you have to extract this particular dot AD file here. Our zip file has been unzipped here and
we can see a folder of dot AD here. You have to open this folder. If I tell you to start, then first of all you
have to open this unzipped folder. You have to open the dot SD folder and you have to extract this
particular dot AD folder here.
You have to open it and tap on the top side, so that you can see the complete path here, you have to
copy this path and after copying, first of all you have to set its path in the environmental variable, so you
have to open this particular environmental variable

And here you have to tap on the page. You have to double tap on the path to the environmental variable.
After double tapping, in the menu you have to tap on the menu here and paste that particular path here. Paste,
OK, OK, and
Again you have to press OK three times, after that you have to close this particular file manager as well and
we will also unminify this here and first of all you have to open the command palette and on the command palette
first of all you have to execute a particular command here whose name is 'pedat' so as soon as I typed 'pedat'
here it automatically captured my SD card or located my SD card and after completing it told me that your
data has been successfully installed here.
If yes, then let us check once whether my version of the SDK is perfect or not. So first of all you have to execute
the command here dot space h version and you have to press enter here. So it has shown my version here or
the version of the SDK is 3.2.4 stable version which is updated on the month of December 21 713 2023. On
that day it was completely updated and the stable version had come. So we have successfully installed the
paid SDK here. Now what do we have to do? We have to do only this and only this, we have to install an editor
for this.
You will also have to install it, so to install the editor we open it again, my VS code which has been successfully
downloaded, let's open it and install it on our system, so first of all we go inside the show in folder and on top of
show in folder first of all I do this, here install I accept the agreement and you have to click next next and again
next create a desktop icon and now we will click here next and install okay so our VS code
It has been successfully installed. Now on top of this particular window system, we pack it here. After
finishing it, we pack it here as well. Close and close again. So now we have this type of interface of VS Code. So
first of all, you have to keep some keys in mind here, like first of all, you have to go to the extensions section and
above the extensions section, first of all, you have to download an extension of dot. Like, you will see brackets of
different types.
Here you will see fts of different types, then how to complete it, it will be managed by Yuzing Dat extension as
well as by Yuzing Rainbow Pro type plugin, okay, so first of all you have to write paid dat here and after writing
dot, in the simple box, you have to enter this particular extension here, install, okay, so our data has
been successfully installed, now first of all we have to come to the folder which contains payfiles here and
now first of all we will have to keep some keys in mind, so first of all you will have to tap control shift and p. As
soon as you press control shift plus p command,
If you execute it then automatically a text box will open in front of you and simply you have to select dot
newproject here and press enter. You have to execute Dart programming here for that particular platform. It means
you have to create a web app, or you have to create an application, or you have to create a console application,
or you have to create a data package or you have to create a server app. So for now I will select the text box
here, console application, and after selecting the console application, it is telling me
,Machine Translated by Google
If you want to keep this particular project in which folder here, then I will tell you the path to it, so
first of all I will come inside C drive and create a new folder on top of C drive, whichever place you
want to keep it in, like you want to keep it in D drive or F drive, if you want to keep this folder in any
particular directory, then you can select that particular folder here, so for now I will take it here and
example dot programs, all the programs of my data will be inside this folder, so select it
Tax
Let us select here and do this. Now here first of all you have to name the project so here first of
all I will name it first program and enter so as I press enter that either automatically my executable
has started here and after the executable starts automatically I have three folders here the first
folder is of bin, the second folder is of hellip the third folder is of test we have all the three folders
here and dot also got successfully created here
It has been installed and even if it has not been completely executed here, a normal, time-tested
program has come to me. Now, here, first of all we will come to the lib folder and above the lib
folder, I will create a new file here, which I will name first dot dot. Always remember that whenever
we create any file in VS Code, you will have to give its extension there, whether you are working on
ATML then dr ATML or you are working on CSS then dot
CSS, if you work on JavaScript then dot GS is same as it is, when you work on dot, you will have
to give its extension dot dot, only then that file will be executable on that particular platform,
so now what you have to do is, you have to write this line here, first of all void main and void
main, after writing it, I will get it printed here, all over I thought, you must have heard it in many
programming languages, hello world, so we will print this particular name here, execute and semi
column, now this
The process of executing is very simple, first of all you have to tap on it, after tapping it will run
automatically on our debug console, so we have the output of this, Hello [Music] World, in normal
course we will create a basic program, so first of all let us open VS code, inside which we will build
programs through programming, so first of all I will open VS code and after opening VS code,
what we saw in the previous session, I have the same
Here the project is open so first of all I create a new project here by pressing control shift p and here
I select dot new program and in this I select console application so at this place we will keep all
the folders of dot so first of all I select that folder here I select this folder here and after selecting
I change its name for example dot application second and enter so automatically I have indexing
here
It has started so let's let it complete. Ok, our indexing has been filled in here. Now first thing we have
to do is come to the lib folder and create a new file above the lib folder. I will name this file test
dt and enter. Whichever file you create, you will have to give its extension dot dt only if you are
programming in dot. If you are programming in other languages then you will have to give its
particular extension like .CAA for SCAA and .CAA for JavaScript.

Through these particular extensions you will be able to identify that file whether this is my JS file or my dot file. So
a dot file has been created here. So first of all I will write a basic program here. So the program is this. First of
all I will write here void main. So if I explain this void main, then void means that this particular function will not
return anything. Void means simply null. When the function is executed, then this function will not return
anything for us.
no, now if I talk about this particular main, then main is that function from where our program starts executing,
for example, you all use a car, then when you put the key in the car and turn on the ignition, then your car starts,
so same as it is, when we want to start executing our program, then what is the key for it, this main function
is its key, so through this main function you can get that particular program executed, so here we have main and
after main you will get this
You will see brackets. Now what is the meaning of these brackets. In programming language we call these
brackets as parameters. Now the simple meaning of parameter is that within this particular brackets you can
pass some parameters, as we will see in the upcoming data series. What are positional parameters, what are
name parameters, then we will use this particular parameter for passing parameters. So whenever you have to
pass parameters, we will use these brackets. And after all you will see this type of brackets here.
We will be calling these brackets curly braces. Wherever you see curly braces, understand that it is the body of
that function. Whatever code you find within these curly braces, then you have to first come within these curly
braces. Whatever you execute the complete program, whatever you build the complete program, it will come
within these curly braces. So for now, first of all I will pass a print here and within this print I will pass it hello world.
So, why did I use this print here?
I created Yuzu only and only for this so that when it is executed, it should appear here as you see above all the
people that you have to fill the user name here and above the password you must also be visible that you
have to fill the password here, so how does that thing which you see come, by using the printing function,
through print you are telling the user that at this place you have to fill the user name and at this place you have
to fill the password, so same as it is, what am I getting printed here, hello world, so that what does the User see,
hello world.
Let's see now why I have written hello world here inside the paddle codes. The simple meaning of double codes
is string. We will use the string whenever we print any C word in our console, then we will use the double
codes. Same as it is, when you execute any new value then double codes will not appear inside the new value.
The double codes will come only and only for your words and after that I have put it here semi column. Now what
is the meaning of semi column, that in this place
Here you will have to read the print function and looking at the semi column what will happen from this place it
will get terminated so I decided to use semicolon or not and after that I also decided to use params or parens
why did I use params because I am passing a parameter inside this print function which
