the_country_number_widgets

A small widgets library for flutter based on the_country_number which doesn't depend on libphonenumber, only pure dart. If you need skip null safety, please use 0.9.0 A simple form-field for international phone number input with realtime validation

//with prefilled number
final currentNumber = TheCountryNumber().parse(internationalNumber:"+97156565656");
TheCountryNumberInput(
  currentNumber,
  onChanged: (tn) {
    _enteredNumber = tn;
    if(_enteredNumber.isValidLength){
      //do something
    }
  }, 
)
//with only prefix
final numberWithOnlyPrefix = currentNumber.removeNumber();
TheCountryNumberInput(
  numberWithOnlyPrefix,
  onChanged: (tn) {
   //even you can check whether its correctly parsed, not needed but library is not even 1.0
    if(tn.isNotANumber()){
     return;
    }
    _enteredNumber = tn;
    if(_enteredNumber.isValidLength){
      //do something
    }
  }, 
)

with your own validation when FormState.validate() is called

final numberWithOnlyPrefix = currentNumber.removeNumber();
TheCountryNumberInput(
  numberWithOnlyPrefix,
  onChanged: (tn) {
    _enteredNumber = tn;
    if(_enteredNumber.isValidLength){
      //do something
    }
  },
  customValidator: (tn) {
    if(tn.isValidLength){
      return null;
    }
    return "Enter a valid number";
  }
)

keep in mind that some countries support phone numbers of multiple lengths, which is supported too
