The temporary solution @pepe-calero referred would look like this:

Add the following section in your pubspec.yaml

dependency_overrides:
  date_range_picker:
    git:
      url: https://github.com/LempereurBenjamin/date_range_picker

Answer 3

Use this,

Deprecated. Please use ButtonBarTheme instead which offers more flexibility to configure ButtonBar widgets.

This feature was deprecated after v1.9.1.

Because ButtonTheme.bar is deprecated.

For reference, https://api.flutter.dev/flutter/material/ButtonTheme/ButtonTheme.bar.html

Answer 4

I just updated flutter and I also keep getting this error. I agree with @PatelFab, ButtonTheme.bar is deprecated. If you are using ButtonTheme.bar "directly" in your code, just change it to ButtonBarTheme.

Another solution would be to use the flutter showDateRangePicker function.

I have the problem of not using ButtonTheme.bar "directly", but another package I depend on uses it: flutter_form_builder. In case you use flutter_form_builder, the issue has already been posted in github and I bet they're working on it.

I'll update when it's solved.
