onColumnTranslate property
Contains a callback that will be called whenever the translation of a column needs to change.
The null value here will result in column movement not animating.
Internal logic assumes that the changes will get applied the next build-cycle. Failing to so will lead to unexpected behavior.
Can be changed at any time (except SchedulerPhase.persistentCallbacks).
Implementation
final ValueNotifier<ColumnTranslateCallback?> onColumnTranslate;
