Question

i'm developing an app related to social messanging and i want to convert big numbers to Human readable format (e.g. 1500 to 1.5k) and also i'm new to Dart. Your help will be appreciated.

Answer 1

Make a class and used its static method every where.

class NumberFormatter{
  static String formatter(String currentBalance) {
    try{
      // suffix = {' ', 'k', 'M', 'B', 'T', 'P', 'E'};
      double value = double.parse(currentBalance);

      if(value < 1000000){ // less than a million
        return value.toStringAsFixed(2);
      }else if(value >= 1000000 && value < (1000000*10*100)){ // less than 100 million
        double result = value/1000000;
        return result.toStringAsFixed(2)+"M";
      }else if(value >= (1000000*10*100) && value < (1000000*10*100*100)){ // less than 100 billion
        double result = value/(1000000*10*100);
        return result.toStringAsFixed(2)+"B";
      }else if(value >= (1000000*10*100*100) && value < (1000000*10*100*100*100)){ // less than 100 trillion
        double result = value/(1000000*10*100*100);
        return result.toStringAsFixed(2)+"T";
      }
    }catch(e){
      print(e);
    }
  }
}
