The package allows you to format phone numbers. for Russian numbers, a mask will be applied. no matter which digit you start entering (from 9.8 or 7), the mask correctly adapts the value in the input field. If you specify a number not from Russia, then the mask will not work
Just download the package to get started.
Declare a mask for formatting
final maskFormatter = RuPhoneInputFormatter();add it to TextForm
TextFormField(
inputFormatters:[maskFormatter],
);get the result in maskFormatter.getClearPhone()
String phone=maskFormatter.getClearPhone();To add a new phone to an already existing mask, use:
final textController=TextFormField();
......
maskFormatter.setPhone("999999999");
textController.text=maskFormatter.getMaskedPhone();
