我有一个 Flutter 插件在我新创建的 Flutter-plugin 项目上成功运行。iOS 和 Android 都能够成功运行这个 Flutter 插件的 example/lib/main.dart 示例代码。
但是,一旦我尝试在另一个 Flutter 项目中使用该插件,就会崩溃。
到目前为止,我已经尝试了两种方法来将我自己编写的插件集成到另一个 Flutter 项目中:
在我的 Flutter 项目中(我尝试使用里面的插件),我转到pubspec.yaml
文件并写:
我尝试了...本地路径集成:
dependencies:
flutter:
sdk: flutter
my_plugin_name:
path: ../../../Flutter_plugins/my_plugin_name/
或者我尝试了...远程集成:
dependencies:
flutter:
sdk: flutter
my_plugin_name:
git:
url: https://github.com/XXXX/my_plugin_name.git
两种集成都可以正常工作,并且 VSCode 似乎可以正确导入插件!
但这就是事情崩溃的地方!只要我添加任何东西dependencies
,那就是事后崩溃的时候。
为了测试它是否有效,我打开我的 Flutter 项目并转到 lib/main.dart:
在我想要将插件集成到的项目的 lib/main.dart 中,我编写的内容与插件项目的 plugin-example 文件夹中的内容几乎相同(请参阅下面的代码)。
或者换句话说,我尝试运行与 plugin-example 文件夹完全相同的代码,但这次是在我的另一个 Flutter 项目中导入了插件。
因此,我将示例代码粘贴到我的 Flutter 项目的 lib/main.dart 文件中。
在 main.dart 中,我添加了以下导入:
import 'package:flutter/material.dart';
import 'dart:async';
import 'package:flutter/services.dart';
import 'package:my_plugin_name/my_plugin_name.dart';
. 并将代码粘贴到 main.dart 中:
void main() => runApp(MyApp());
class MyApp extends StatefulWidget {
@override
_MyAppState createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
String _platformVersion = 'Unknown';
@override
void initState() {
super.initState();
initPlatformState();
}
// Platform messages are asynchronous, so we initialize in an async method.
Future<void> initPlatformState() async {
String platformVersion;
// Platform messages may fail, so we use a try/catch PlatformException.
try {
platformVersion = await MyPluginNameClass.getVersion;
} on PlatformException {
platformVersion = 'Failed to get platform version.';
}
// If the widget was removed from the tree while the asynchronous platform
// message was in flight, we want to discard the reply rather than calling
// setState to update our non-existent appearance.
if (!mounted) return;
setState(() {
_platformVersion = platformVersion;
});
}
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(
title: const Text('Plugin example app'),
),
body: Center(
child: Text('$_platformVersion\n'),
),
),
);
}
}
编译器此时没有给我任何错误或警告。一切似乎都很好。
但是,如果我构建并运行,我会得到世界、IOS 和安卓的错误例外 - 为什么??????
在 iOS 上,错误消息是:

有人知道在这里做什么吗?
集成本地或远程 Flutter-plugin 时我错过了什么?
