WKeyboardActions(
focusNodes: [_nameFocus, _amountFocus],
toolbarClassName: 'bg-gray-100 dark:bg-gray-800',
child: Column(
children: [
WInput(focusNode: _nameFocus, placeholder: 'Jane Doe'),
WInput(
focusNode: _amountFocus,
placeholder: '0.00',
type: InputType.number,
),
],
),
)
Basic Usage#
Create a FocusNode for each input field and pass them all in the focusNodes list. WKeyboardActions attaches listeners to every node and shows the toolbar as long as any one of them is focused.
class _MyFormState extends State<MyForm> {
final _nameFocus = FocusNode();
final _amountFocus = FocusNode();
@override
void dispose() {
_nameFocus.dispose();
_amountFocus.dispose();
super.dispose();
}
@override
Widget build(BuildContext context) {
return WKeyboardActions(
focusNodes: [_nameFocus, _amountFocus],
child: Column(
children: [
WInput(focusNode: _nameFocus, placeholder: 'Full Name'),
WInput(
focusNode: _amountFocus,
placeholder: '0.00',
type: InputType.number,
),
],
),
);
}
}
Constructor#
const WKeyboardActions({
Key? key,
required Widget child,
required List<FocusNode> focusNodes,
String platform = 'all',
bool nextFocus = true,
String? toolbarClassName,
Widget Function(FocusNode)? closeWidgetBuilder,
})
Props#
| Prop | Type | Default | Description |
|---|---|---|---|
child |
Widget |
Required | The form or column of inputs the toolbar is attached to. |
focusNodes |
List<FocusNode> |
Required | FocusNodes for the inputs that need keyboard actions. Order determines navigation order. |
platform |
String |
'all' |
Platform gate: 'all', 'ios', or 'android'. |
nextFocus |
bool |
true |
When true, Previous/Next arrow buttons appear in the toolbar for field navigation. |
toolbarClassName |
String? |
null |
Wind utility classes applied to the toolbar background (typically bg-* classes). |
closeWidgetBuilder |
Widget Function(FocusNode)? |
null |
Builder that replaces the default "Done" button. Receives the currently-focused FocusNode. |
Platform Targeting#
The platform prop gates the toolbar to a specific OS. The most common value is 'ios', because iOS numeric keyboards have no built-in Done button.
| Value | Toolbar visible on |
|---|---|
'all' |
iOS and Android (default) |
'ios' |
iOS only |
'android' |
Android only |
WKeyboardActions(
platform: 'ios',
focusNodes: [_amountFocus],
child: WInput(
focusNode: _amountFocus,
placeholder: '0.00',
type: InputType.number,
),
)
Navigation Between Fields#
When nextFocus: true (the default), the toolbar shows Previous and Next arrow buttons. They move focus to the previous or next node in the focusNodes list, in the order they were provided. The Previous button is disabled at the first field; the Next button is disabled at the last.
Set nextFocus: false to show only the Done button, which is useful for single-field forms.
WKeyboardActions(
focusNodes: [_nameFocus, _emailFocus, _amountFocus],
nextFocus: true,
child: Column(
children: [
WInput(focusNode: _nameFocus, placeholder: 'Jane Doe'),
WInput(focusNode: _emailFocus, placeholder: '[email protected]'),
WInput(focusNode: _amountFocus, placeholder: '0.00'),
],
),
)
Toolbar Styling#
Pass Wind bg-* utility classes via toolbarClassName to set the toolbar background. The dark: pair is required.
WKeyboardActions(
toolbarClassName: 'bg-gray-100 dark:bg-gray-800',
focusNodes: [_focusNode],
child: myInputField,
)
When toolbarClassName is null, the toolbar uses Theme.of(context).colorScheme.surfaceContainerHighest.
Custom Close Button#
Supply closeWidgetBuilder to replace the default "Done" label with any widget. The builder receives the currently-focused FocusNode, which you can call unfocus() on.
WKeyboardActions(
focusNodes: [_focusNode],
closeWidgetBuilder: (node) => WButton(
onTap: node.unfocus,
className: 'bg-blue-600 text-white px-4 py-1.5 rounded-md text-sm font-medium',
child: const WText('Save & Close', className: 'text-white text-sm font-medium'),
),
child: myInputField,
)
Styling Examples#
Minimal (single field, iOS only)#
WKeyboardActions(
platform: 'ios',
nextFocus: false,
focusNodes: [_amountFocus],
toolbarClassName: 'bg-white dark:bg-gray-900',
child: WInput(
focusNode: _amountFocus,
placeholder: '0.00',
type: InputType.number,
),
)
Multi-field form with custom toolbar color#
WKeyboardActions(
focusNodes: [_nameFocus, _emailFocus, _amountFocus],
toolbarClassName: 'bg-blue-50 dark:bg-blue-950',
child: Column(
children: [
WInput(focusNode: _nameFocus, placeholder: 'Jane Doe'),
WInput(focusNode: _emailFocus, placeholder: '[email protected]'),
WInput(focusNode: _amountFocus, placeholder: '0.00'),
],
),
)
Custom close widget#
WKeyboardActions(
focusNodes: [_focusNode],
toolbarClassName: 'bg-emerald-50 dark:bg-emerald-900',
closeWidgetBuilder: (node) => TextButton.icon(
onPressed: node.unfocus,
icon: const Icon(Icons.check_circle_outlined),
label: const Text('Done'),
),
child: myInputField,
)
