I am opening whatsapp url with text and number.
Issue is i have 2 types of number
+923323789222 & 03323789222
Whatsapp is not opening number starting from 0 so what i need to do is if number have 0 replace it with +92
var url ='whatsapp://send?phone=+923323789222&text=Apna ${widget.data['selererName']} ko ${Ggive.toString()} Rupees dene hein';
in phone when i am passing with +92 its working fine so my question is how can i replace if my number start with 0 and replace with +92
You can just check if your number have 0 in start just replace with +92 and if its not start with 0 then remain it same.
String num = yournumber.toString();
if(num[0] == "0"){
print('have zero');
String numb2 = num.substring(0, 0) + "+92" + num.substring(1);
print(numb2);
num = numb2;
}
var url ='whatsapp://send?phone=${num}&text=Apna ${widget.data['selererName']} ko ${Ggive.toString()} Rupees dene hein';
print(url);
Just use the below code to replace a particular string.
var url ='whatsapp://send?phone=+923323789222&text=Apna ${widget.data['selererName']} ko ${Ggive.toString()} Rupees dene hein';
url.replaceAll('phone=0', 'phone=+92');
You can also use regex for string replacement.
Try this:
String formatPhoneNumber(String phoneNumber) {
if (phoneNumber.length < 1) return '';
// if the phone number doesn't start with 0,
// it is already formatted and we return in the
// way it is.
if (phoneNumber[0] != '0') return phoneNumber;
// if it starts with 0 then we replace the 0 with +92
// and return the new value.
return phoneNumber.replaceFirst(RegExp('0'), '+92');
}
Usage:
print(formatPhoneNumber('+923323789222'));
// OUTPUT: +923323789222
print(formatPhoneNumber('03323789222'));
// OUTPUT: +923323789222
