Flutter Firestore 导致 D8:Android Studio 中的单个 dex 文件(# 方法:71610 > 65536)中无法容纳请求的类 [英] Flutter Firestore causing D8: Cannot fit requested classes in a single dex file (# methods: 71610 > 65536) in Android Studio

问题描述

我正在尝试在最新版本的 Android Studio 中将 firestore 与 Flutter 应用程序一起使用.我完全遵循了这些说明.https://www.youtube.com/watch?v=DqJ_KjF;list=PLjxrf2q8roU2HdJQDjJzOeO6J3FoFLWr2&index=9 上周我什至让他们使用不同的应用程序工作.现在，当我在完成(包括)更新 pubspec.yaml 之前的所有步骤后尝试运行我的新应用程序时，出现以下错误.请记住，在这个例子中，我在一个新的 flutter counter 应用程序上遇到了错误，除了你在这里看到的之外，没有其他代码更改.

I am attempting to use firestore with a Flutter app in latest version of Android Studio. I have followed these instructions exactly. https://www.youtube.com/watch?v=DqJ_KjFzL9I&list=PLjxrf2q8roU2HdJQDjJzOeO6J3FoFLWr2&index=9 I even got them to work last week with a different app. Now I get the following error when I attempt to run my new app after completing all the steps up to (and including) updating pubspec.yaml. Keep in mind, in this example, i am getting the error on a fresh flutter counter app with no other code changes but what you see here.

D8: Cannot fit requested classes in a single dex file (# methods: 71610 > 65536)

description: A new Flutter application.

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# In Android, build-name is used as versionName while build-number used as versionCode.

  # To add assets to your application, add an assets section, like this:

  # To add custom fonts to your application, add a fonts section here,
  # in this "flutter" section. Each entry in this list should have a
  # "family" key with the font family name, and a "fonts" key with a
  # list giving the asset and other descriptors for the font. For

推荐答案

启用 multidex.

打开 project/app/build.gradle 并添加以下几行.

Open project/app/build.gradle and add the following lines.

defaultConfig {
    ...

    multiDexEnabled true
}

和

dependencies {
    ...

    implementation 'com.android.support:multidex:1.0.3'
}

如果你已经迁移到 AndroidX，你会想要这个(提示来自 Toure Holder):

If you have migrated to AndroidX, you'll want this instead (tip by Touré Holder):

dependencies {
    ...

    implementation 'androidx.multidex:multidex:2.0.1'
}
