How do I swap two letters for another in a String in Flutter?

I’m using the code below to replace the letters "êm" with "em", but it’s not working.

str = str.replaceAll('êm', 'em');

I want to use the code to remove the accents only from some specific words such as: "crêem", "vêem", "dêem". I can’t do a general code, because other words like "têm" need to be kept with the accent.

    Just replace the accent ê with e:

      String s = 'vêem';
  
  s = s.replaceAll('ê' , 'e');
  
  print(s);

    Which prints:

    veem

    You can achieve this by below code:

    void main() {
  String str = "Eles crêem que vêem e dêem mas têm que aprender.";
  
  // Use a map to define the replacements
  Map<String, String> replacements = {
    'crêem': 'creem',
    'vêem': 'veem',
    'dêem': 'deem'
  };
  
  // Replace only the specified words
  str = str.replaceAllMapped(RegExp(r'b(?:crêem|vêem|dêem)b'), (match) {
    return replacements[match.group(0)]!;
  });
  
  print(str); // Eles creem que veem e deem mas têm que aprender.
}
