TextField controlled controller.addListener(() gets called multiple time after pressing the clear button, this will only happen if we are clearing it.
Snippet:
TextEditingController controller = new TextEditingController();
TextField field = new TextField(
controller: controller,
autofocus: true,
);
controller.addListener(() {
print("Pressed cancel button");
});

Note: While adding characters in TextField listener method gets called only ones.
I guess that would be a defect on flutter, a possible solution would be to use onChanged()
TextField field = new TextField(
autofocus: true,
onChanged: (String value) {
print("Pressed clear button");
},
);
I have the same problem with Nexus 6p when used with API level 23 and Pixel with API 25.
but this problem did not occurs with Pixel with API28 and it does not occurs with Nexus6P with API26.
exact code from https://flutter.dev/docs/cookbook/forms/text-field-changes was used.
void clearField() {
print("c: clearField");
var newValue = textController.value.copyWith(
text: '',
selection: TextSelection.collapsed(offset: 0),
);
textController.value = newValue;
callApi('');
}
// and call it by :
child: TextField(
controller: textController,
autofocus: true,
decoration: InputDecoration(
suffixIcon: IconButton(
icon: Icon(Icons.close),
onPressed: clearField, // call
),
),
),
void changesOnField() {
print("c: changesOnField");
String text = textController.text;
if (text.isNotEmpty) { // set this
callApi(text);
}
}
