How to add values to a Map and finally that map to a list (Dart).

main.dart

void main() {
  List<Map> _pecasList = [];
  List<String> alphas = ["a", "b", "c"];

  Map<String, dynamic> newPecas = Map();

  for (String c in alphas) {
    if (c.isEmpty || c.trimLeft() == "") {
      print("Campo Vazio");
    } else {
      newPecas["title$c"] = c.trimLeft();
    }
  }
  _pecasList.add(newPecas);
  print(_pecasList);
}
