Todo App is not working properly

Schokiii93 · Oct 3, 2022

Hi guys,

I’m currently developing a todo app. What I already implemented is:

possibility to register and login (Firestone)
created a firestore database to save new todos
todos stored in database will be displayed on homepage
button to be able to create new todos

Now, I want to implement a new form to create a new todo and to change the existing ones. To do so, I created a new bloc and already implemented. Now, I’m getting a very confusing error message which I can’t fix. The error is displayed in the android emulator:
‘package: flutter/src/widgets/framework.dart’ : Failed assertion: line 4606 pos 14: ‘owner! ._debugCurrentBuildTarget == this’ : is not true.

Here is my code:
https://github.com/Schokiii93/todo

I also get a bunch of error messages in the terminal:

#1 new Todo.empty (package:todo/domain/entities/todo.dart:30:59)
