Issue: Cannot theme progress indicators, many properties missing #131690
Description
Is there an existing issue for this?
- I have searched the existing issues
- I have read the guide to filing a bug
Steps to reproduce
The ProgressIndicatorThemeData is missing many key properties from LinearProgressIndicator and CircularProgressIndicator making it impossible to theme their styles.
Expected results
Expect to be able to style the LinearProgressIndicator and CircularProgressIndicator with their ProgressIndicatorThemeData by also adding styles for properties:
borderRadiusThe border radius of both the indicator and the linear track on aLinearProgressIndicator.strokeWidthThe width of the line used to draw the circle on aCircularProgressIndicator.strokeAlignThe relative position of the stroke on aCircularProgressIndicator.strokeCapThe progress indicator's line ending on aCircularProgressIndicator.
Actual results
The newer LinearProgressIndicator and CircularProgressIndicator properties listed above that were added as enhancements, e.g. in PR #122664 were forgotten or neglected to be added to ProgressIndicatorThemeData and are now missing, this is causing theming issues.
The properties cannot be found in the latest version of ProgressIndicatorThemeData:
Therefore, we cannot theme the LinearProgressIndicator and CircularProgressIndicator to their desired style.
