• ‘ThemeData’ is from ‘package:flutter/src/material/theme_data.dart’ (‘/C:/flutter/FlutterDev/flutter/packages/flutter/lib/src/material/theme_data.dart’).
  Try correcting the name to the name of an existing getter, or defining a getter or field named ‘backgroundColor’.

final color = decoration.color ?? Theme.of(context).backgroundColor;
