Build release APK failed with some material theme error

Question

My application working well and when I try to generate build release apk it throws me error:

../../.pub-cache/hosted/pub.dev/helpers-1.2.0/lib/helpers/misc.dart:127:7: Error: No named parameter with the name 'window'.
      window: ui.window,
      ^^^^^^

- 'ThemeData' is from 'package:flutter/src/material/theme_data.dart' ('../../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 'accentColor'.
  Color get accent => Theme.of(_context).accentColor;
                                         ^^^^^^^^^^^

Answer 1

The error indicates that it is in the package helpers. Try updating the helpers package. I see there is version 1.2.3 now. So edit your pubspec.yaml to use that version. It looks like older versions use properties of ThemeData that no longer exist. The latest version fixes this.
