flutter - flutter 如何比较两个不同格式的电话号码

我正在尝试查找两个电话号码是否相同(两个相同的电话号码可能格式不同，因为[phone]与9998245345和99982 45345相同)

最佳答案

为此，可以使用contains() Dart 字符串方法。我将尾随语句标记为粗体，因为它适用于String。确保以字符串格式获取数字，或将其转换为字符串，然后执行操作。

代码

// this is a comparision between [phone] and other numbers
// you can play around and get what you want
void main() {
  var _inputPhone = "[phone]";
  var _checkPhone = "9998245345";
  var _anotherCheck = "99982 45345";

  // checking that white space removal works or not
  print(_anotherCheck.replaceAll(new RegExp(r"\s+"), ""));

  // I have just removed the spaces from the number which had the white
  // space, you can store the value using this code for every data
  // for unknown data coming from server side or user side
  _anotherCheck = _anotherCheck.replaceAll(new RegExp(r"\s+"), "");
  if(_inputPhone.contains(_anotherCheck)){
    print('99982 45345 and [phone] are same');
  }

  if(_inputPhone.contains(_checkPhone)){
    print('9998245345 and [phone] are same');
  }

}

输出

9998245345
99982 45345 and [phone] are same
9998245345 and [phone] are same
