getAdaptiveButtons static method

Iterable<Widget> getAdaptiveButtons(
  1. BuildContext context,
  2. List<ContextMenuButtonItem> buttonItems
)

Returns a List of Widgets generated by turning buttonItems into the default context menu buttons for the current platform.

This is useful when building a text selection toolbar with the default button appearance for the given platform, but where the toolbar and/or the button actions and labels may be custom.

This sample demonstrates how to use getAdaptiveButtons to generate default button widgets in a custom toolbar.
