telephoneNumberCountryCode constant
The input field expects a phone number's country code.
This hint will be translated to the below values on different platforms:
- Android: AUTOFILL_HINT_PHONE_COUNTRY_CODE.
- web: "tel-country-code".
- Otherwise, the hint string will be used as-is.
Implementation
static const String telephoneNumberCountryCode = 'telephoneNumberCountryCode';
