如何在flutter中将数字格式化为指数形式

dependencies:
  flutter:
    sdk: flutter
  flutter_localizations:
    sdk: flutter
  intl: ^0.17.0

import 'package:intl/intl.dart';

void main() {
  double number = 1234567890.123456789;

  NumberFormat formatter = NumberFormat.scientificPattern();

  String formattedNumber = formatter.format(number);

  print(formattedNumber); // 输出：1.2345678901234568E9
}
