WHAT IS FLUTTER?

To be able to answer this question, First let’s assume that there’s one whose name is Bob and he's an iOS developer. He has developed an ios application based on grocery, it is very efficient and useful for the customers. So customers have demanded that when that application will be available in play store that means in android. Now bob has to develop that application in android so he has to maintain codebases which are ios as well as android which seems difficult and that app must run efficiently in all iPhone models as well as in android models with each and every screen size. That means our application UI must remain the same in iPad as well as in tablets also. So here comes flutter in the scene.



So what is flutter? Flutter is an open-source SDK that is used to build native-looking applications like android and ios from the same code base.


WHY WE USE FLUTTER:

By using flutter we can develop ios application as well as android application with the same codebase and it is the best cross-platform tool.

 

WHICH PROGRAMMING LANGUAGE DOES FLUTTER USE:


Flutter uses dart language that is strongly typed language. I mean statically typed.

It is developed by Google.

It also supports jit compilation that is just in time compilation. 

So there would be faster compilation during the development that means whenever we make changes in our code the output will be reloaded faster in our emulator or in our devices with no time that is also called a hot reload. 

It also supports AOT compilation that is ahead of time compilation. When our app is released in the market user can experience better faster and efficient execution of our application. So that would be advantageous for developers as well as for users as flutter provides jit compilation as well as AOT compilation.

 

HOW TO INSTALL FLUTTER:

STEPS FOR INSTALLING FLUTTER:


  1. Go to your browser and type flutter.dev and hit the get started button. 
  2. Select your OS options (Windows, MAC, etc). 
  3. Download flutter SDK
  4. Go to a specified location and extract that zip folder and then you will get flutter folder.
  5. Go over there and go in bin folder. 
  6. Now copy the location and search environment variables. 
  7. Now go for environment variables and in the system variables edit the path variable. 
  8. Hit new and paste your location. 
  9. And that’s it, you have successfully installed flutter in your device.
  10. To check that just open the command prompt and type flutter version.
  11. You will get your flutter version as well as your dart version.
