Flutter：cloud_firestore的构建错误：版本“ 0.7.4”以上 [英] Flutter: Build errors for cloud_firestore: above version "0.7.4"

问题描述

我已经尝试解决了几个小时的构建问题，直到我意识到这是由于Flutter插件cloud_firestore引起的。 0.7.4版适用于Android和iOS，但0.7.4以上的任何版本（如0.8.2 + 1）都会出现以下错误：

I have been trying to resolve a build issue for hours until I realise it is due to Flutter plugin cloud_firestore. Version 0.7.4 builds fine for both Android and iOS but anything above 0.7.4 like 0.8.2+1 will have errors such as:

我想为两个ios使用0.8.2 + 1 cloud_firestore和Android，因为

I would like to use 0.8.2+1 cloud_firestore for both ios and Android because of the support of

await db.settings(timestampsInSnapshotsEnabled: true);

在这里感谢一些帮助。非常感谢！

Appreciate some help here. Many Thanks!

推荐答案

我觉得你，我也花了很多小时试图解决这个问题。

I feel you, I've also spent hours and hours trying to figure this out.

构建SSCCE，然后将该项目的设置应用于我的项目，然后进行一些调整，我的项目就可以正常工作。

After building a SSCCE, and then applying the settings of that project to my project, and then some tweaking, I got my project working.

尽管我调整的设置超出了我的记忆力，但这些设置似乎影响最大：

Although I adjusted more settings than I care to remember, these seem to have had the highest impact:

在 pubspec.yaml ：

# included two other common libraries others might use
cloud_firestore: 0.8.2+1
firebase_auth: 0.7.0
google_sign_in: 3.2.4

明确禁用 android / gradle.properties 中的这两个功能：

Explicitly disable these two features in android/gradle.properties :

android.useAndroidX=false
android.enableJetifier=false

在<$ c $中使用这些版本的依赖项c> android / build.grade ：

dependencies {
    classpath 'com.android.tools.build:gradle:3.2.1'
    classpath 'com.google.gms:google-services:4.2.0'
}

最后，在 android / app / build.gradle 中使用以下设置：

And finally, use these settings in android/app/build.gradle:

android {
    compileSdkVersion 27
    ...
    defaultConfig {
        ...
        minSdkVersion 21
        targetSdkVersion 28
        multiDexEnabled true
        ...
    }
    ...
}
...
dependencies {
    implementation 'com.google.firebase:firebase-core:16.0.1'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    compile 'com.android.support:multidex:1.0.3'
}

还值得注意的是，我下载了 google-services.json 再次文件（尽管仅对b无效）本身）。

It's also worth noting that I downloaded the google-services.json file again (though that didn't have any effect just by itself).

这些设置的任何组合都可能对您有所帮助。

Any combination of these settings might help you.
