Migration Guide

From version 2.x

The following breaking API changes have been made in version 3.0:

  • The parameter animationDuration has been moved from Expandable to ExpandableController. This was done in order to simplify combining multiple Expandable widgets and to make animationDuration available to ScrollOnExpand.

  • The parameter initialExpanded has been removed from ExpandablePanel. If you need to make anExpandablePanel expanded initially, wrap it with an ExpandableNotifier or pass an ExpandableController.

  • The constructor of ExpandableController accepts named parameters. Provide the initial value by calling ExpandableController(initialExpanded: myValue).

From version 1.x

When Expandable was initially created, it was using Scoped Model plugin for communicating state changes. In version 2.0.0 the dependency on ScopedModel was eliminated.

This is a breaking change, so a code change is necessary to make the code work. The migration is mainly a search/replace:

  • ScopedModel<ExpandableModel> -> ExpandableNotifier
  • ExpandableModel -> ExpandableController
  • ScopedModel.of<ExpandableModel> -> ExpandableController.of
