如何使用Firebase崩溃分析在Flutter应用程序中解混淆Java堆栈跟踪

Question

在我的firebase控制台中，我可以看到以下崩溃:

Fatal Exception: io.flutter.plugins.firebase.crashlytics.FlutterError: Bad state: Cannot add event after closing. Error thrown null.

我正在使用最新的Firebase pub(来自pubspec.lock):

firebase_crashlytics:
dependency: "direct main"
description:
name: firebase_crashlytics
url: "https://pub.dartlang.org"
source: hosted
version: "2.8.2"
firebase_crashlytics_platform_interface:
dependency: transitive
description:
name: firebase_crashlytics_platform_interface
url: "https://pub.dartlang.org"
source: hosted
version: "3.2.8"

我能做什么来获得一个可读的堆栈跟踪?

p。此外，这是非常令人困惑的问题似乎发生在Dart代码，但我可以看到Java文件在堆栈跟踪..

pp。我已经配置了android项目的混淆如下:

release {
signingConfig signingConfigs.googleplaySigningConfig
minifyEnabled true
debuggable false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard.cfg'
firebaseCrashlytics {
mappingFileUploadEnabled true
nativeSymbolUploadEnabled true
unstrippedNativeLibsDir "build/app/intermediates/merged_native_libs/release/out/lib"
}
ndk {
debugSymbolLevel 'FULL'
}
}

Answer 1

Crashlytics最近增加了对使用--split-debug-info和--obfuscate构建的Flutter应用程序的支持。

如果你正在使用这些参数构建应用，请尝试将Crashlytics SDK升级到最新版本。
