android - 找不到 com.google.firebase :firebase-crashlytics flutter

Question

我在 flutter 方面没有经验，但已经做了一段时间。我当前的项目正在使用 firebase，所以我使用的是 flutterfire 包，这一定是我迄今为止最糟糕的噩梦。构建失败后构建失败。注意 IOS 正在运行。最近的是这个

FAILURE: Build failed with an exception.

* What went wrong:
Could not determine the dependencies of task ':firebase_crashlytics:compileDebugAidl'.
> Could not resolve all task dependencies for configuration ':firebase_crashlytics:debugCompileClasspath'.
   > Could not find com.google.firebase:firebase-crashlytics:.
     Required by:
         project :firebase_crashlytics

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

您需要实现应用级gradle文件app/build.gradle中的依赖

// Add the Firebase Crashlytics SDK.
    implementation 'com.google.firebase:firebase-crashlytics:17.2.2'
    // Recommended: Add the Google Analytics SDK.
    implementation 'com.google.firebase:firebase-analytics:18.0.0'

dependencies 部分应该是这样的

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'com.android.support:multidex:1.0.3'
    // Add the Firebase Crashlytics SDK.
    implementation 'com.google.firebase:firebase-crashlytics:17.2.2'
    // Recommended: Add the Google Analytics SDK.
    implementation 'com.google.firebase:firebase-analytics:18.0.0'
}

我希望这能解决您的问题。
