How to dispose a list of text editing controllers in Flutter-CodePudding

I want to know what is the right way to dispose all text editing controllers in a list in flutter?

List<TextEditingController> controllers = [];

I tried this, but it's not working. What should be the correct approach for it?

dispose(){
 for(TextEditingController controller in controllers){
     controller.dispose();
  }
}

CodePudding user response：

You are trying to call dispose on your List<TextEditingController>and not on your TextEditingController. You need to change it inside your for loop body.

dispose() {
 for(final TextEditingController controller in controllers){
     controller.dispose();
  }
}

CodePudding user response：

You are calling on wrong variable:

@override
void dispose() {
  for (TextEditingController controller in controllers) {
      controller.dispose(); //<-- change this
  }
  super.dispose();
}
