[xmkg]

This release does not play well with Flutter 3.29.0:

The current Dart SDK version is 3.7.0-323.0.dev.

Because extended_text 15.0.0 requires SDK version >=3.7.0 <4.0.0 and no versions of extended_text match >15.0.0 <16.0.0, extended_text ^15.0.0 is forbidden.
So, because multipass_gui depends on extended_text ^15.0.0, version solving failed.


You can try one of the following suggestions to make the pubspec resolve:
* Try using the Flutter SDK version: 3.29.0. 
* Consider downgrading your constraint on extended_text: flutter pub add extended_text:^14.2.0
