根据我的研究，我发现我可能需要升级到 AndroidX.我按照这个 link 来升级我的 android.但是，在尝试构建和运行应用程序时，我仍然遇到相同的错误.
From my research I found that i might need to upgrade to AndroidX. I followed this link to upgrade my android. However i still got the same errors when trying to build and run the app.
我使用 InteliJ 作为我的 IDE 和 flutter 项目，我的 pubspec.yaml 如下:
I am using InteliJ as my IDE with a flutter project and my pubspec.yaml is as follows:
name: smart_diet_flutter
description: A new Flutter project.
# 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.
# Read more about versioning at semver.org.
version: 1.0.0+1
environment:
sdk: ">=2.0.0-dev.68.0 <3.0.0"
dependencies:
flutter:
sdk: flutter
# The following adds the Cupertino Icons font to your application.
# Use with the CupertinoIcons class for iOS style icons.
cupertino_icons: ^0.1.2
firebase_auth: 0.8.0
firebase_database: 1.1.0+1
dev_dependencies:
flutter_test:
sdk: flutter
# For information on the generic Dart part of this file, see the
# following page: https://www.dartlang.org/tools/pub/pubspec
# The following section is specific to Flutter.
flutter:
# The following line ensures that the Material Icons font is
# included with your application, so that you can use the icons in
# the material Icons class.
uses-material-design: true
# To add assets to your application, add an assets section, like this:
# assets:
# - images/a_dot_burr.jpeg
# - images/a_dot_ham.jpeg
# An image asset can refer to one or more resolution-specific "variants", see
# https://flutter.io/assets-and-images/#resolution-aware.
# For details regarding adding assets from package dependencies, see
# https://flutter.io/assets-and-images/#from-packages
# 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
# example:
# fonts:
# - family: Schyler
# fonts:
# - asset: fonts/Schyler-Regular.ttf
# - asset: fonts/Schyler-Italic.ttf
# style: italic
# - family: Trajan Pro
# fonts:
# - asset: fonts/TrajanPro.ttf
# - asset: fonts/TrajanPro_Bold.ttf
# weight: 700
#
# For details regarding fonts from package dependencies,
# see https://flutter.io/custom-fonts/#from-packages

推荐答案
您要么需要迁移到 AndroidX，要么需要降级到与 AndroidX 之前版本兼容的插件版本.
You either need to migrate to AndroidX or downgrade to the plugin versions that are compatible with pre-AndroidX.
关注https://github.com/flutter/flutter/issues/27106 关于与迁移相关的问题(另见 https://github.com/flutter/flutter/问题/27146、https://github.com/flutter/flutter/issues/27128 对于与您的问题相同的错误输出)
Follow https://github.com/flutter/flutter/issues/27106 about issues related to the migration (see also https://github.com/flutter/flutter/issues/27146, https://github.com/flutter/flutter/issues/27128 for the same error output as in your question)
另见
重大变化.从已弃用的原始 Android 支持库迁移到 AndroidX.这不应导致任何功能更改，但它需要任何使用此插件的 Android 应用程序也进行迁移 如果他们使用的是原始支持库.
Breaking change. Migrate from the deprecated original Android Support Library to AndroidX. This shouldn't result in any functional changes, but it requires any Android apps using this plugin to also migrate if they're using the original support library.
