CodePudding user response：

Try running these commands:

flutter clean
flutter packages get
dart pub get

CodePudding user response：

It happens usually when you put @required in your code and dart accidentally auto includes 'dart:html' as well.

If you don't have any usage of it then try removing it, then it'll work.

CodePudding user response：

You are most likely running into the issue, that dart:html is not available on all target platforms. It should only be used for web development.
