Here is a simple example of how auto focus a CupertinoSearchTextField after navigating to the page in Flutter
Problem
In Flutter, a Textfield or in my case a CupertinoSearchTextField does not auto focus on page load. I want it to. Here's how.
1) Define a FocusNode in your StatefulWidget
Then in initState(), slap on a delay to wait for the page transition as you wish.
class _MyPageState extends State<MyPage> {
FocusNode _node = FocusNode();
// ....
@override
void initState() {
super.initState();
Future.delayed(Duration(milliseconds: 350)).then((_) {
FocusScope.of(context).requestFocus(_node);
});
}
2) Attach the FocusNode to the CupertinoSearchTextField:
Widget _buildSearchBox() {
return CupertinoSearchTextField(
focusNode: _node,
// ...
);
}
Conclusion
Now when you push the page with that widget, you'll get it auto-focusing.
Hope this helps!
