substring() flutter

Comment

substring(): allows you to pick a specific part or data at the start or end of a string.
Ex: String firstEntry='Mike';
firstEntry.substring(1); // Takes first letter at the start of the variable and gives 'ike'
firstEntry.substring(1,2); // Takes first letter at the start and last 2 at the end of the string and gives 'i'

  final startIndex = str.indexOf(start);
  final endIndex = str.indexOf(end, startIndex + start.length);

  print(str.substring(startIndex + start.length, endIndex)); // brown fox jumps
