Flutter TextField FocusNode not gaining focus back [FocusNode "NOT FOCUSABLE"]

Question

I have a TextField with a focusNode that suddenly stops gaining focus after changing screens. One thing I notice though, the object changes its value canRequestFocus to false for no reason.

FocusNode value before launching other Widget:

FocusNode#1502a(context: EditableText-[LabeledGlobalKey<EditableTextState>#26e29])

FocusNode value after launching other Widget and TextField doesn't get focus when I tap:

FocusNode#1502a(context: EditableText-[LabeledGlobalKey<EditableTextState>#26e29], NOT FOCUSABLE)

The problem doesn't happen on Android.

I've created this Sample Project and this Video showing how to reproduce the issue.

Answer 1

I encountered the same issue today, with Flutter version 3.22.1. My solution was to use a custom subclass of FocusNode to create the focus node:

class _FocusNode extends FocusNode {
  @override
  bool get canRequestFocus => true;
}

This overrides the problematic variable, and makes the text field always focusable.
