Details

When using the feedbackBuilder parameter to build a custom feedback interface, components that make use of ThemeExtensions are unable to do so because FeedbackThemeData does not propagate extensions.

This is similar to #317, but feels a separate issue is warranted because that thread suggests that this conflict between BetterFeedback and the host Theme is "fixed", but the root cause still exists and this can't really be worked around AFAIK.

Steps to reproduce

• git clone this repository
• cd feedback-repro
• flutter run

In the default state (useExtensions set to true) you will get a runtime Exception when showing feedback. Flip useExtensions to false in main.dart and no issues will occur (because the extension is not accessed).
