Flutter

• Its a toolkit, that makes it easy for devloper to desgin a beautiful interfaces for all souce of devices
• It just takes blank screen of ur ANDROID/IOS and draws on it
• We just make use of few pre-built widgets to make our user interfaces which look like its made in native code.

Why Flutter

1. One CodeBase -> Its a cross-platflorm , write the code once and it runs on both the platform of IOS and ANDROID.
2. One Language -> Dart is Language which we used to build apps (ANDROID and IOS) and webapps
3. Hot Reloading -> When the changes are made , it will be reflecting on spot
4. Access to Original Source Code -> Flutter is Open Source, so we can access the original source code of flutter and can make changes if needed
5. Flexible and Simple Layout System

   • Constraint Based Layout

     Every parent widget tells its child widget:

     👉 “This is how big (or small) you’re allowed to be.”
