Offline plugin: java.lang.IllegalStateException - Missing theme on OfflineActivity

I received the following crash log from Firebase Crashlytics:

Fatal Exception: java.lang.RuntimeException: Unable to start activity ComponentInfo{com.cohenadair.anglerslog/com.mapbox.mapboxsdk.plugins.offline.ui.OfflineActivity}: java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.

Environment:

• Android 8.1.0, Nexus 5X
• I'm using the unofficial Flutter plugin: https://github.com/flutter-mapbox-gl
• The Flutter plugin uses:

    dependencies {
        implementation "com.mapbox.mapboxsdk:mapbox-android-sdk:9.6.2"
        implementation "com.mapbox.mapboxsdk:mapbox-android-plugin-annotation-v9:0.9.0"
        implementation "com.mapbox.mapboxsdk:mapbox-android-plugin-localization-v9:0.12.0"
        implementation 'com.mapbox.mapboxsdk:mapbox-android-plugin-offline-v9:0.7.0'
    }

Notes:

• I'm not quite sure how to reproduce it. I loaded a map on an Android 8 (and 12) emulator while not having an internet connection, and although the map appeared black, the app did not crash.

OfflineActivity のエントリポイントから始め、offline plugin によって起動されたときに Android テーマがどのように設定されるかを調べてください。提供された Mapbox SDK と offline plugin のバージョンを使って、報告された起動失敗を再現してみてください。OfflineActivity が報告された AppCompat テーマ例外なしで起動すれば完了です。
