Original version: https://github.com/flutter/flutter/issues/104548#issuecomment-1683714851 Next version: https://gist.github.com/Schwusch/edf778492423db42a0ad11efd5bc8727 This version: https://gist.github.com/bryantwilliam/62a2b4cbd390a0e62612b3ea85c7f5e9 A widget that transforms the text selection when copied.
This uses the SelectionContainer with a custom SelectionContainerDelegate to override the
getSelectedContent method with a custom implementation.
Use this by wrapping a subtree under SelectionArea, e.g:
SelectionArea(
child: SelectionTransformer.separated(
child: Column(children: [
Text("Hello"),
Text("World"),
]),
),
)
