我一直在尝试开发一个与FireBase一起工作的应用程序，我不是编码专业人士。
实际上，我的应用程序在模拟器上运行良好，但3-5秒后，我会收到一条错误消息，如下所示：

W/DynamiteModule(11855): Local module descriptor class for providerinstaller not found.
I/DynamiteModule(11855): Considering local module providerinstaller:0 and remote module providerinstaller:0
W/ProviderInstaller(11855): Failed to load providerinstaller module: No acceptable module found. Local version is 0 and remote version is 0.
W/DynamiteModule(11855): Local module descriptor class for providerinstaller not found.
I/DynamiteModule(11855): Considering local module providerinstaller:0 and remote module providerinstaller:0
W/ProviderInstaller(11855): Failed to load providerinstaller module: No acceptable module found. Local version is 0 and remote version is 0.

你可以看到我的依赖关系如下：

除了上面的providerinstaller问题，当我尝试用相机上传图像时，我得到下面的其他错误：

如果你想看我的代码或其他文件，我想与你分享。你能请指导我吗？
先谢谢你了。
艾金，你好

2021年7月更新：
对于为什么会出现这些警告，没有明确的答案，但可以遵循一些步骤。
1.确保在所有三个AndroidManifest.xml文件（即debug/main/profile）中定义了<uses-permission android:name="android.permission.INTERNET"/>。
对于一些人来说，在主AndroidManifest文件中包含<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />也有帮助。
1.有时过时的google play服务也会导致这些警告，所以更新google play服务这主要发生在模拟器的情况下。
1.如果您在较旧的设备上运行应用程序，请确保用户已启用多媒体功能。
要启用multi-dex支持，请将以下代码添加到
应用程序/build.gradle文件

defaultConfig {
        applicationId "com.example.flutter_test_firebase"
        minSdkVersion 16
        targetSdkVersion 30
        multiDexEnabled true  //<= add this line
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
    }

并在同一文件中添加以下依赖项

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation("com.android.support:multidex:1.0.3") // for multi-dex
}

还要确保您使用的是最新的firebase插件。

我不知道你在哪里访问了firestore包，但在我的情况下，我试图更新数据，但我实际上是删除和创建一个新的，其中没有我需要在我的代码访问的数据。所以我唯一的建议是走了，确保你不是意外删除数据或试图访问数据，你不't或将不会有一些未知的原因去你的firestore数据库，并确保你的数据是你想要的。我已经看到答案说，你需要更新你的谷歌服务在您的模拟器，所以也许这可能是你的情况下，但它不是我的，如果你去你的谷歌播放服务应用程序在设置和看到取消激活意味着你的模拟器已经更新了，它会说更新你的谷歌播放器服务。

我得到了同样的错误，当我的应用程序在模拟器中启动，也当我点击添加新数据按钮。实际上，我的问题正是添加新数据到Firebase Firestore在Flutter。
我更新了Google Play服务，它对我很有效。
要更新Google Play服务，请执行以下操作：

文件〉设置〉外观和行为〉系统设置〉Android SDK〉SDK工具，然后选择Google Play服务和更新。

希望能成功。

make sure that <uses-permission android:name="android.permission.INTERNET"/> is defined in all the three AndroidManifest.xml files that i.e debug/main/profile.

这对我很有效
