dart - Disable a text edit field in flutter

Question

I need to disable TextFormField occasionally. I couldn't find a flag in the widget, or the controller to simply make it read-only or disable. What is the best way to do it?

Answer 1

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.
