如何在flutter中读取txt文件？

import 'dart:async';
import 'dart:io';

void main() {
  readTxtFile();
}

void readTxtFile() {
  File file = File('path/to/your/file.txt');
  if (file.existsSync()) {
    Stream<List<int>> inputStream = file.openRead();
    inputStream.transform(utf8.decoder).transform(LineSplitter()).listen(
      (String line) {
        print(line);
      },
      onDone: () {
        print('File reading complete');
      },
      onError: (e) {
        print(e.toString());
      },
    );
  } else {
    print('File not found');
  }
}
