The build method is called any time you call setState , your widget’s dependencies update, or any of the parent widgets are rebuilt (when setState is called inside of those). Your widget will depend on any InheritedWidget you use, e.g. Theme. of(context) , MediaQuery. of(context) etc.16 Ağu 2019
How build method works how it rebuild itself?
There are six sets, because whenever you run the Flutter app, the setState() calls the build() method and it displays the number 0 on the screen. Next, each time you press the button, it rebuilds the descendant widget trees also. If we quit the app and restarts the app again, it starts with a fresh display of a screen.22 May 2021
