Возникновение пожара Flutter, вызывающее D8: невозможно разместить запрошенные классы в одном файле dex (# методы: 71610> 65536) в Android Studio

Я пытаюсь использовать FireStore с приложением Flutter в последней версии Android Studio. Я точно следовал этим инструкциям. https://www.youtube.com/watch?v=DqJ_KjFzL9I&list=PLjxrf2q8roU2HdJQDjJzOeO6J3FoFLWr2&index=9 Я даже заставил их работать на прошлой неделе с другим приложением. Теперь я получаю следующую ошибку, когда пытаюсь запустить свое новое приложение после выполнения всех шагов до (и включая) обновления pubspec.yaml. Имейте в виду, что в этом примере я получаю сообщение об ошибке в новом приложении счетчика флаттера без изменений кода, кроме того, что вы видите здесь.

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

Ответ 1

Включить мультидекс.

Откройте project/app/build.gradle и добавьте следующие строки.

defaultConfig {
    ...

    multiDexEnabled true
}

и

dependencies {
    ...

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

Если вы перешли на AndroidX, вам это нужно (совет от Touré Holder):

dependencies {
    ...

    implementation 'androidx.multidex:multidex:2.0.1'
}

Ответ 2

По умолчанию Flutter поддерживает Android SDK v16 (Jelly Bean, выпущенный в 2012 году), но multidex на самом деле не работает с Jelly Bean "из коробки".

A) Изменить минимальный целевой SDK

  1. Откройте android/app/build.gradle, затем найдите строку с надписью minSdkVersion 16.
  2. Измените эту строку на minSdkVersion 21.
  3. Сохраните файл.

Б) Включить мультидекс.

Если вы хотите поддерживать более старые версии Android, вы можете использовать библиотеку поддержки multidex.

  1. Откройте и измените файл project/app/build.gradle, чтобы включить мультидекс, и добавьте мультидексную библиотеку в качестве зависимости, как показано здесь:
android {
    defaultConfig {
        ...
        multiDexEnabled true
    }
    ...
}

dependencies {
  compile 'com.android.support:multidex:1.0.3'
}

Ответ 3

Добавьте это в android/app/build.gradle:

defaultConfig {
    ...
    multiDexEnabled true
}
