Goal: when send button is pressed, don't close the keyboard and keep it open/focused Problem: when send button is pressed, keyboard is closed, then reopens because of focusNode.requestFocus, when send button is pressed after that, the keyboard doesn't open anymore Looking for two options:
- (ideal) Don't let the keyboard close when send button is pressed
- (okay) Open keyboard no matter how many times send button is closed
Here is sample UI:
return Form(
key: _formKey,
child: Row(
children: <Widget>[
Expanded(
child: TextFormField(
focusNode: chatController.focusNode,
// textInputAction: TextInputAction.none, // didn't help
// onEditingComplete: () {}, // didn't help
)
),
IconButton(
icon: const Icon(Icons.send),
onPressed: () async {
SystemChannels.textInput
.invokeMethod('TextInput.hide');
if (_formKey.currentState!.validate()) {
await chatController.sendMessage(context);
}
}
),
],
)
);
Here is controller:
late FocusNode focusNode;
@override
void onReady() async { // tried onInit as well
focusNode = FocusNode();
super.onReady();
}
void sendMessage(BuildContext context) async {
// focusNode.unfocus(); // didn't help
// focusNode2.requestFocus(); // tried to give focus to another widget and take it back, but didn't help
final a1 = focusNode.hasFocus; // except the very first call, this is true even when focusNode.unfocus() is called
// neither of these work the second time
focusNode.requestFocus();
// FocusScope.of(context).requestFocus(focusNode);
}
I was able to trace code and when second call gets to focus manager here this condition is always true:
if (hasPrimaryFocus && (_manager!._markedForFocus == null || _manager!._markedForFocus == this)) {
even though the keyboard is closed, and it returns without attempting to open the keyboard again
CodePudding user response:
You have a stray:
SystemChannels.textInput.invokeMethod('TextInput.hide');
in your IconButton
callback, it should work after removing it.
