If you want to do the same here, process all textfields with the same controller. Here, the structure is reset when switching to a different request, you can clear the controller in the selection.

can you give me example demo code file please help.

[aydemiromer]

late final TextEditingController _textController;

String qrText = '';
@OverRide
void initState() {
super.initState();
_textController = TextEditingController(text: qrText);
}

SizedBox _qr() {
return SizedBox(
height: context.height * 0.4,
child: Center(
child: QrImage(
data: qrText,
version: QrVersions.auto,
size: 200,
gapless: false,
),
),
);
}
Padding myTextFormFieldUrl() {
return Padding(
padding: const EdgeInsets.all(8.0),
child: TextFormField(
controller: _textController,
onChanged: (value) => setState(() {
qrText = value;
}),
decoration: InputDecoration(
border: InputBorder.none,
labelText: LocaleKeys.home_page_text_field_label_url.tr(),
),
),
);
}

You can use one more time textform with controller

Please suggest multiple text-filed data in single barcode.
