• 'BuildContext' is from 'package:flutter/src/widgets/framework.dart' ('/C:/src/flutter/packages/flutter/lib/src/widgets/framework.dart'). Try correcting the name to the name of an existing method, or defining a method named 'inheritFromWidgetOfExactType'. context.inheritFromWidgetOfExactType(_ProgressTheme); ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Failed to compile application.

I am using this progress dialog library to show progress UI when app is performing something serious IO stuff. But i noticed when we double tap or long press on any Text Input Field, App crashed / shows Red screen in debug.

Here is the related logs:

Text input field setup in other screen as follow:

                            color: Theme.of(context).primaryColor,
                          ),
                        ),
                        decoration: BoxDecoration(

                      ),
                    ),

I don't see any proper solution as of now. Please help me here to resolve this issue. Else i might need try and switch over to other library and that some extra work. Thanks.

The method inheritFromWidgetOfExactType(T) was deprecated after v1.12.1, and totally replaced by dependOnInheritedWidgetOfExactType<T>() on version 1.26.0-12.0.pre-dev.

the visual display is very nice. one thing lacking is that the user can click anywhere on the screen. the behavior should still be the same as a dialog where clicking anywhere will dismiss it, or have an option to not dismiss it and can only do so programmatically.
