我最近开始了一个新的 Flutter 项目。目前这个项目还很简陋。只有几个文件和一些基本的软件包，如 riverpod 和 intl，用于本地化。

每当我在本地机器上运行 flutter analyze 时，我当前的分支上都没有问题。在 flutter clean 和 flutter pub get 等之后，情况仍然相同。

但是，当我提交并将此分支推送到 Gitlab 时，我在 CI 中调用的 flutter analyze 确实产生了三个问题，这些问题似乎与无法找到或访问 intl 包有关。

这是我的 Gitlab CI 文件：

analyse:
    stage: test
    image: "cirrusci/flutter:stable"
    before_script:
    - export PATH="$PATH":"$HOME/.flutter-sdk/.pub-cache/bin"
    - flutter pub get
    - flutter --version
    script:
        - flutter analyze

test:
    stage: test
    image: "cirrusci/flutter:stable"
    before_script:
    - export PATH="$PATH":"$HOME/.flutter-sdk/.pub-cache/bin"
    - flutter pub get
    script:
        - flutter test -j 1 test

版本调用是为了确保 Flutter 和 Dart 版本在 Gitlab 和本地是相同的。

这是分析阶段的输出：

所有问题都发生在主文件中，如下所示：

import 'package:flutter/material.dart';
import 'package:flutter_localizations/flutter_localizations.dart';
import 'package:flutter_riverpod/flutter_riverpod.dart';
import 'package:kook_app/ui/app/app_page.dart';

import 'l10n/l10n.dart';

void main() {
  runApp(const KookApp());
}

class KookApp extends StatelessWidget {
  const KookApp({super.key});

  @override
  Widget build(BuildContext context) {
    return ProviderScope(
      child: MaterialApp(
        localizationsDelegates: const [
          S.delegate,
          GlobalMaterialLocalizations.delegate,
          GlobalWidgetsLocalizations.delegate,
          GlobalCupertinoLocalizations.delegate,
        ],
        supportedLocales: const [
          Locale('en', 'UK'),
          Locale('nl'),
        ],
        debugShowCheckedModeBanner: false,
        title: 'KookApp',
        theme: ThemeData(
          primarySwatch: Colors.blue,
        ),
        home: const AppPage(),
      ),
    );
  }
}

文件本身也没有报告 Android Studio 中的任何问题。
