General

What bug do you experience? 🐞

"'package:flutter/src/widgets/framework.dart': Failed assertion: line 2685 pos 20: '_debugCurrentBuildTarget == context': is not true." when message content is larger than screen size

How can it be reproduced? 🤔

A few steps to define where does the bug occur. Step 1. add messages until the existing screen size is exceeded

What behavior is expected? 💡

I wish no more errors
