Framework: Make ScrollPhysics reactive by introducing shouldUpdate
aae16ca 
This commit allows ScrollPhysics subclasses to update their parameters without requiring a change in runtimeType.

By overriding shouldUpdate, physics classes can return true to signal that their internal parameters have changed and the ScrollPosition should adopt the new physics, resolving long-standing bugs with physics updates.

Code Review

This pull request introduces a shouldUpdate method to ScrollPhysics, allowing subclasses to trigger a ScrollPosition update when rebuilt with a new physics instance of the same type. ScrollableState is updated to evaluate this method, and a test suite is added to verify the behavior. The review feedback suggests overriding shouldUpdate in built-in subclasses with configuration parameters, such as BouncingScrollPhysics, to ensure they react correctly to parameter changes.

Code Review

This pull request introduces a shouldUpdate method to ScrollPhysics to allow subclasses to trigger a ScrollPosition update when configuration parameters change, updates ScrollableState to evaluate this method, and adds corresponding tests. Feedback suggests refactoring the conditional check in ScrollableState into two separate if statements to avoid using the bang operator (!) and leverage Dart's flow analysis for non-nullable type promotion.

Thank @Mairramer!
Making ScrollPhysics reactive via shouldUpdate is sound and follows existing Flutter framework patterns (CustomPainter.shouldRepaint, ScrollBehavior.shouldNotify), however there is a runtime TypeError bug in ScrollPhysics.shouldUpdate:

When a wrapper physics has its parent changed to a subclass with a covariant-narrowed parameter (such as BouncingScrollPhysics.shouldUpdate(covariant BouncingScrollPhysics old)), invoking parent!.shouldUpdate(old.parent!) throws a runtime _TypeError if old.parent has a different runtime type (e.g. ClampingScrollPhysics).

I've left inline comments on the specific lines with detailed rationale and suggested fixes.

autosubmit label was removed for flutter/flutter/189664, because - The status or check suite Dashboard Checks has failed. Please fix the issues identified (or deflake) before re-applying this label.
