enableInteractiveSelection property
final
Whether to enable user interface affordances for changing the text selection.
For example, setting this to true will enable features such as long-pressing the TextField to select text and show the cut/copy/paste menu, and tapping to move the text caret.
When this is false, the text selection cannot be adjusted by the user, the cut/copy/paste menu is hidden, and the shortcuts to cut/copy/paste text do nothing but stop propagation of the key event to other key event handlers in the focus chain.
Defaults to true.
Implementation
final bool enableInteractiveSelection;
