Changing focus from one text field to the next in Flutter - flutter

Question

I have two textFormField widgets. Once the user has completed the first text field I would like to focus on the next textField. Is there a way to do this in Flutter? Currently, the done button just closes the keyboard. I was guessing the focusNode class might be the answer to this but not really sure how that works does anyone have any good examples of focusNode class? Thanks in advance.

Answer 1

Yes, FocusNode and the onFieldSubmitted from a TextFormField are probably the way to go.
FocusScope.of(context).requestFocus(focusNode);
Here is an example that may help:
FocusNode textSecondFocusNode = new FocusNode();
TextFormField textFirst = new TextFormField(
onFieldSubmitted: (String value) {
FocusScope.of(context).requestFocus(textSecondFocusNode);
},
);
TextFormField textSecond = new TextFormField(
focusNode: textSecondFocusNode,
);
// render textFirst and textSecond where you want
You may also want to trigger FocusScope.of() from a button rather than onFieldSubmitted, but hopefully the above example gives you enough context to construct an appropriate solution for your use case.

Answer 2

Screenshot:
No need to use FocusNode
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(),
body: Column(
children: [
TextField(
decoration: InputDecoration(hintText: 'First Name'),
textInputAction: TextInputAction.next,
onEditingComplete: () => FocusScope.of(context).nextFocus(),
),
TextField(
decoration: InputDecoration(hintText: 'Last Name'),
textInputAction: TextInputAction.done,
onSubmitted: (_) => FocusScope.of(context).unfocus(),
),
],
),
);
}

Answer 3

There's a similar method like in Android.
Add
textInputAction
parameter to the TextFormField Widget, then add the property as;
TextInputAction.next

Answer 4

This is how I did it:
var _focusNodes = List.generate(6, (index) => FocusNode()));
And in the TextFormField:
TextFormField(
focusNode: _focusNodes[i],
maxLines: 1,
textInputAction: TextInputAction.next,
onChanged: (text) {
if (i < _controllers.length) {
if (text.isEmpty)
_focusNodes[i - 1].requestFocus();
else
_focusNodes[i + 1].requestFocus();
}
},
),
