How to convert text file asset into List<String> - flutter

Question

May I ask, How do i read a plaintext, located at assets/plaintext.txt, with the following content
1st line
2nd line
3rd line
and convert it into something, which act like, the following would have
List<String> stri = <String>[
"1st line",
"2nd line",
"3rd line",
];
The following code makes the app screen go black
import 'dart:core';
import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
String stri = '0';
Future<void> main() async {
stri = await rootBundle.loadString('assets/plaintext.txt');
runApp(
const MyApp(),
);
}
Thanking you...

You can load a string first using rootBundle.loadString() method, and then construct a list out of a pattern.
import 'dart:async' show Future;
import 'package:flutter/services.dart' show rootBundle;
void loadAsset() async {
String loadedString = await rootBundle.loadString('assets/plaintext.txt');
List<String> result = loadedString.split('\n');
}
Don't forget to add it in your pubspec.yaml
flutter:
assets:
- assets/plaintext.txt
