showToolbar method

@override bool showToolbar()

Shows the selection toolbar at the location of the current cursor.

Returns false if a toolbar couldn't be shown, such as when the toolbar is already shown, or when no text selection currently exists.

Implementation

@override
bool showToolbar() {
  // Web is using native dom elements to enable clipboard functionality of the
  // toolbar: copy, paste, select, cut. It might also provide additional
  // functionality depending on the browser (such as translate). Due to this
  // we should not show a Flutter toolbar for the editable text elements.
  if (kIsWeb) {
    return false;
  }

  if (_selectionOverlay == null || _selectionOverlay!.toolbarIsVisible) {
    return false;
  }

  _selectionOverlay!.showToolbar();
  return true;
}
