Whatever code I select, I can't see if it is selected or not.

The first code block I actually selected.
The second, I didn't.

Maybe add a color to SelectableText widget.

Tried to build apk.

When I deploy the App for flutter web the Back-Buttons not working anywhere in the App.

hi, first of all, I want to thank you for your amazing repo,

I just noticed that in the referenced function (stopStreaming) you turned the lights On which is already on, based on your previous function (startStreaming), and is there any reason to add turnLightsOn() again?

thank you in advance for your clarification

void startStreaming(SmartHomeState smartHomeState) {
smartHomeState.lightsOn = smartHomeApi.turnLightsOn();
smartHomeState.tvOn = tvApi.turnOn();
gamingFacade.startStreaming(smartHomeState);
}

void stopStreaming(SmartHomeState smartHomeState) {
gamingFacade.stopStreaming(smartHomeState);
smartHomeState.tvOn = tvApi.turnOff();
smartHomeState.lightsOn = smartHomeApi.turnLightsOn();
}

Trying to install app by instructions in readme:

StreamController.broadcast() seems redundant, maybe try to modify it to StreamController().

Although it looks like the ObserverExample uses the stockStream.listen() twice, but since the two StreamControllers are different, So there will be no error exception, it may not be necessary to use StreamController.broadcast().

Hi , thanks for your amazing and inspiring repo,
I just found that in this File class, you didn't implement the 'accept' method of the iFile interface despite that you have used 'implement' keyword here

build failed running in ios

It would be nice to zoom images provided in the markdown files of the design patterns.

This feature is already implemented with #24, but due to changes in the codebase and migration to Dart null-safety the code is already outdated and this solution should be reworked.

can i publish your work(app) in playstore? i like to study when travelling. by the way awesome work.

Good work!

Currently using flutter_windows_2.10.1-stable.

Build failed due to use of deprecated Android v1 embedding.

You can try to delete android:name="io.flutter.app.FlutterApplication".
