needsDelegateRebuild property

  1. @protected
bool needsDelegateRebuild

Should be used by subclasses to invalidate any cached data from the delegate.

This value is set to false after layoutChildSequence. If markNeedsLayout is called withDelegateRebuild set to true, then this value will be updated to true, signifying any cached delegate information needs to be updated in the next call to layoutChildSequence.

Subclasses are not required to use this value, but it can be used to safely cache layout information in between layout calls.


bool get needsDelegateRebuild => _needsDelegateRebuild;
