Flutter AutofillHints oneTimeCode doesn't work

Question

I want to catch OTP sms code but it doesn't work on IOS. I need show the code upper of keyboard.

my code block is;

TextField(
 controller: controller,
 autofillHints: const <String>[AutofillHints.oneTimeCode],
 keyboardType: TextInputType.number,
 onChanged: onChanged,
),

Solution

From Flutter docs at https://master-api.flutter.dev/flutter/material/TextField/autofillHints.html "Some autofill hints only work with specific keyboardTypes". Try changing the keyboardType. For example:

TextField(
 controller: controller,
 autofillHints: const <String>[AutofillHints.oneTimeCode],
 keyboardType: TextInputType.text,
 onChanged: onChanged,
),
