Different ways to replace string

str_manipulation.dart

void main() {
  String str = "one.two";
  print(str.replaceAll(".two", ""));
  
  // or
  
  print(str.split(".").first);// split() will split from . and gives new List with separated elements.
  
  // or
  
  print(str.substring(0, str.indexOf("."))); // substring from start character to firstly found dot
  
  
  // or
  
  String newStr = str.replaceRange(str.indexOf("."), str.length, "");
  print(newStr);
  
  // another example
  String nums = "1,one.2,two.3,three.4,four";
  List values = nums.split(".");
  values.forEach(print);
  
  //output
  
//   1,one
//   2,two
//   3,three
//   4,four
