flutter_dynamic_themes's Issues

Feedback

Hey, I'm using https://github.com/Norbert515/dynamic_theme in an app but the project is not maintained anymore. I found your project as an alternative however your implementation doesn't solve my use case:

I need to be able to dynamically define a new theme at runtime, for instance, an app where the user could change the colors with an RGB picker and customs everything. This means I cannot provide a list of pre-defined themes, this was possible with Norber515's project.

Let me know if you do some changes in the future that would solve that.

Thanks, and great work with your package!

[Flutter 2.0] Null check operator used on a null value

I just got the same error today.

Worst thing about this error is that it it crashes even before the app is visible, since the DynamicTheme is the wrapper of the MaterialWidget

Error message:

======== Exception caught by widgets library =======================================================
The following _CastError was thrown building Builder:
Null check operator used on a null value

The relevant error-causing widget was: 
  Builder file:///C:/tools/flutter/.pub-cache/hosted/pub.dartlang.org/provider-4.3.3/lib/src/inherited_provider.dart:162:13
When the exception was thrown, this was the stack: 
#0      State.widget (package:flutter/src/widgets/framework.dart:1062:26)
#1      new _DynamicThemeState (package:dynamic_themes/src/dynamic_theme.dart:79:23)
#2      DynamicTheme.createState (package:dynamic_themes/src/dynamic_theme.dart:58:39)

#4      StatefulWidget.createElement (package:flutter/src/widgets/framework.dart:916:38)

main file code sample:

return DynamicTheme(
      themeCollection: ThemeUtils.collection, // {Light, Dark, Custom}
      defaultThemeId: AppTheme.Light, // AppTheme.Light = 0, int value
      builder: (_, theme) => MaterialApp(
        title: 'Demo app,
        theme: theme,
        home: buildApp(),
        debugShowCheckedModeBanner: false,
      ),
    );

@JulianAssmann Please check this issue and let me know if there's any work arounds for this. I'll be looking forward to resolution of this issue.

Unexpected null value.

Add default light/dark theme with optional automatic theme detection
