I have four textfields, a title field, a details field, a date field, and a time field. Both the date and time fields are wrapped within a gesture detector, and onTap calls a pickDateAndTime method. The problem is that when I click on the date field and try to manually change the time through the input rather than the dial way, the focus goes to the title field and when I am still on the time picker and type something in the time picker, the title field gets changed with the new input. The weird part is that this error just appeared out of nowhere, and there are no errors reported in the console.

CodePudding user response：
Add a focusNode in your textField:
FocusNode focusNode = FocusNode();
TextField(
focusNode: focusNode,
);
And then in the gesture detector, add that following code to unselect the textfield input:
FocusScope.of(context).requestFocus(FocusNode());
CodePudding user response：
simply wrap your Scaffold widget GestureDetector and add FocusScope.of(context).requestFocus(FocusNode()); it will automatically unfocused text field when you click anywhere on your screen
GestureDetector(
onTap: () {
FocusScope.of(context).requestFocus(FocusNode());
},
child: Scaffold()
)
CodePudding user response：
You can use below code to remove focus in gesture detector event
FocusScopeNode currentFocus = FocusScope.of(context);
if (!currentFocus.hasPrimaryFocus && currentFocus.focusedChild != null) {
currentFocus.unfocus();
}
