Bloc: Access to Bloc in different Pages and refresh event with BlocListener

[Vash1]

Hello there!

After going trough issues #74 #763 #776 I have to ask a question myself, I have uploaded the minimal (not) working code here: https://github.com/Vash1/flutter_weather_settings

The Problem:
Triggering the Toggle event on a Switch on Page2 works. But after returning to Page1 and again going to Page2, the initialState is fired again, resetting my choice.

My Analysis so far:
Following the advices I mentioned, this issue is gone
BlocProvider.of() called on a context that does not contain a Bloc of type SettingsBloc. No ancestor could be found starting from the context ...
But somehow my code ended up with 2 BlocProviders, leading to multiple instatiations of the SettingsBloc.

Maybe I ended up with 2 Instances of the same bloc in different contexts? Or am not refreshing/listening for changes on my HomePage properly? Because also the "Center Text $state.xyz" on my Page1 always stays unchanged when I return from Page2.
This already took me a good amount of time so now I had to ask, and I'm very grateful for advices and help.

Thanks.

Hi @Vash1 👋
Thanks for opening an issue!

I've opened a pull request to address the issue. You were creating multiple instances of the SettingsBloc rather than reusing the existing instance when navigating to the SettingsPage.

Hope that helps 👍
