There are couple of ways to do it :

  1. Using recase package
  2. Using extension methods
import 'package:recase/recase.dart';

void main() {
  print("my_name_is_john_doe".sentenceCase); //snake_case to normal sentence;
  print("myNameIsJohnDoe".sentenceCase); //camelCase to normal Sentence;
  print("my_name_is_john_doe".snakeCasetoSentenceCase()); //Other way of converting snake case to Normal Sentence
}

extension StringExtension on String {
  String snakeCasetoSentenceCase() {
    return "${this[0].toUpperCase()}${this.substring(1)}"
        .replaceAll(RegExp(r'(_|-)+'), ' ');
  }
}

Output:

My name is john doe
My name is john doe
My name is john doe

Flutter Only Solution , as get does not support pure dart

You can try this :

String text = 'myNameIsJohnDoe';

RegExp exp = RegExp(r'(?<=[a-z])[A-Z]');

String result = text.replaceAllMapped(exp, (Match m) => (' ' + m.group(0))).capitalizeFirst;

print('Result : $result');

Output :

 Result : My name is John doe

#UPDATE :

Installing get to use capitalizeFirst

dependencies:
  get: ^4.1.4

Import it , Now in your Dart code, you can use:

import 'package:get/get.dart';
