Disable a text edit field in flutter

There is another way this can be achieved which also does not cause this issue. Hope this might help someone.

Create AlwaysDisabledFocusNode and pass it to the focusNode property of a TextField.

class AlwaysDisabledFocusNode extends FocusNode {
  @override
  bool get hasFocus => false;
}

then

new TextField(
    enableInteractiveSelection: false, // will disable paste operation
    focusNode: new AlwaysDisabledFocusNode(),
    ...
    ...
)

Update:
TextField now has enabled property. Where you can just disable the TextField like

new TextField(
    enabled: false, 
    ...
    ...
)

Note: This will also disable icon associated with text input.
