Flutter 应用程序仅在发布模式下崩溃

Question

我有一个 Flutter 应用程序，它在通过 Android Studio 以调试模式安装时运行良好，在发布模式下登录后崩溃。 我从 Play 管理中心获取了崩溃报告：

我的 pubsec.yaml 依赖项是：

version: 1.0.0+3

environment:
  sdk: ">=2.1.0 <3.0.0"

dependencies:
  flutter:
    sdk: flutter

  cupertino_icons: ^0.1.2
  shared_preferences: ^0.4.3
  connectivity: ^0.4.3+1
  firebase_auth: ^0.11.1+6
  geolocator: ^5.0.1
  cloud_firestore: ^0.12.11
  flutter_blue: 0.6.2
  intl: ^0.15.8
  random_string: ^0.0.2
  flutter_datetime_picker: ^1.2.4
  permission_handler: ^3.1.0

dev_dependencies:
  flutter_test:
    sdk: flutter

  font_awesome_flutter: ^8.0.1

我尝试更新 cloud_firestore 插件，但由于我在稳定频道上，我无法升级到 0.13.0+1 版本，因为所需的最低 Flutter 版本是 1.10.0 并且我使用的是版本

Flutter 1.9.1+hotfix.6 • channel stable • https://github.com/flutter/flutter.git
Framework • revision 68587a0916 (3 months ago) • 2019-09-13 19:46:58 -0700
Engine • revision b863200c37
Tools • Dart 2.5.0

此外，cloud_firestore 0.13.0 给出了以下错误：

Invalid argument(s): Minimum version ("0.13.0") must be less than maximum ("0.13.0-0").

This is an unexpected error. Please run


    pub --trace '--verbosity=warning' get --no-precompile




and include the logs in an issue on https://github.com/dart-lang/pub/issues/new
pub get failed (1)

Answer 1

解决这个问题

flutter build apk --no-shrink

Answer 2

尝试在命令行运行flutter pub cache repair并从 Android Studio 同步您的 gradle 文件。

之后您可能会出现 Android X 错误。 如果您愿意，可以简单地迁移到 Android X

迁移到 Android X： https : //flutter.dev/docs/development/androidx-migration

Answer 3

所以我通过改为 Flutter Master Channel 并升级到：

Flutter 1.13.1-pre.94 • channel master • https://github.com/flutter/flutter.git
Framework • revision 36e599eb5d (2 days ago) • 2019-12-11 07:27:13 +0100
Engine • revision 12bf95fd49
Tools • Dart 2.7.0 (build 2.7.0-dev.2.1 8b8894648f)

此外，我将 Cloud Firestore 升级到最新版本，因为我发现这是导致崩溃的插件。

然后我不得不将依赖项从 Android > Build.gradle 升级到：

classpath 'com.android.tools.build:gradle:3.3.1'

此外，我将 pubsec.yaml 中的所有插件升级到最新版本并修复了所有重大更改。

在此之后，flutter clean 然后flutter build apk，一切正常。

Answer 4

您可以使用 flutter build apk --no-shrink 。 它会起作用。 但推荐的方法是更新您的 flutter sdk 以及您在 pubspec.yaml 文件中使用的依赖项。
