Replace all %@ in string

Created with <3 with dartpad.dev.

main.dart

void main() {
  // Define the input string with placeholders
  String inputString = "Hello, %@! How are you, %@, %@?";

  // Define an array of replacement strings
  List<String> replacements = ["Alice", "Bob"];
  
  print(replaceInString(inputString, replacements));
}

String replaceInString(String inputString, List<String> replacements) {
  String result = inputString.replaceAllMapped(RegExp(r'%@'), (match) {
    if (replacements.isEmpty) {
      return "null";
    } else {
      return replacements.removeAt(0);
    }
  });
  return result;
