I want to make a long list of texts selectable using the SelectionArea widget.

Since all the texts do not fit on a screen, I need to put them inside the scrollable widget such as SingleChildScrollView or ListView

I've added padding to some widgets and marked some others as unselectable by wrapping them inside theSelectionContainer.disabled() widget

Now, I can make the texts selectable by adding the SelectionArea widget either as a parent or child of the scrollable widget.

  • Having the SelectionArea widget as a parent allows users to scroll up/down with the selection, but if the long press starts from either the padding area or unselectable widget, it throws '!_selectionStartsInScrollable': is not true. exception.
return SelectionArea(
  child: SingleChildScrollView(
    child: Text('Lorem Ipsum...'),
  ),
);

  • Having the SelectionArea widget as a child of the scrollable widget, we can avoid the '!_selectionStartsInScrollable': is not true. exception, but users cannot automatically scroll up/down to change the selection.
return SingleChildScrollView(
  child: SelectionArea(
    child: Text('Lorem Ipsum...'),
  ),
);

The question is: Is there a way to make a long list of texts that NEEDS to be scrollable ALSO selectable without seeing the exception?

Steps to Reproduce

  1. Execute flutter run on the code sample on a mobile or tablet device
  2. Try to select the texts and change the selection by moving your fingers up/down and left/right
  3. Now, do the same thing starting from the padding area or unselectable widget

Expected results:

No exception is thrown.

Actual results:

Below exception is thrown:

Another exception was thrown: 'package:flutter/src/widgets/scrollable.dart': Failed assertion: line 1131 pos 14: '!_selectionStartsInScrollable': is not true.
