Unhandled Exception: inheritFromWidgetOfExactType(_LocalizationsScope) or inheritFromElement() was called before _ScreenState.initState() completed

Question

I am calling initial method to load data from API using initState. But it is resulting me an error. Here is error:

Unhandled Exception: inheritFromWidgetOfExactT         


        

Answer 1

Use the didChangeDependencies method which gets called after initState.

For your example:

@override
void initState() {
  super.initState();
}

@override
void didChangeDependencies() {
  super.didChangeDependencies();

  this._getCategories();
}

void _getCategories() async {
  // Omitted for brevity
  // ...

 }
