Question

Я пытаюсь создать APK-файл для этого приложения, но получаю непонятные ошибки. Я искал эту платформу и Github, но никто не помогает. Как я могу решить эту проблему?

Я думаю, что плагин, вызывающий эту ошибку, может быть таким: sqflite: ^1.3.2+1.

Answer 1

Я ошибся в key.propertiesфайл. В файле поменял storeFile переменная из пути, где key.jksбыл сохранен только в key.jks, и сборка прошла успешно.

Answer 2

У меня была такая же проблема неделю назад, я выполнил следующие шаги, чтобы исправить эту ошибку.

В папке android > gradle > wrapper > gradle-wrapper.properties Измените distributionUrl на https\://services.gradle.org/distributions/gradle-5.6.2-all.zip

После этого пробега flutter pub cache repair. Как только он будет завершен без ошибок. Огонь flutter clean и перезапустите приложение после удаления с эмулятора / тестового телефона, ошибка должна была исчезнуть.

Answer 3

попробуйте использовать ниже:

      implementation 'org.tensorflow:tensorflow-lite-metadata:0.1.0-rc2'
