【问题描述】：
当我尝试构建发布 apk 时，出现此错误：

在颤振问题和颤振文档中进行一些搜索后，我看到了一些与我的问题相同的问题。 在调试模式下，当我尝试在 android 手机上运行 app install 时没有任何问题，并且运行良好。但后来我尝试了这些命令：
flutter clean
flutter build apk
我遇到了顶级错误。 这是我的 pubspec.yaml 文件：
name: atlas_gen_demo
description: A new Flutter project.
# The following line prevents the package from being accidentally published to
# pub.dev using `pub publish`. This is preferred for private packages.
publish_to: "none" # Remove this line if you wish to publish to pub.dev
# 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.
# Read more about Android versioning at https://developer.android.com/studio/publish/versioning
# In iOS, build-name is used as CFBundleShortVersionString while build-number used as CFBundleVersion.
# Read more about iOS versioning at
# https://developer.apple.com/library/archive/documentation/General/Reference/InfoPlistKeyReference/Articles/CoreFoundationKeys.html

environment:
sdk: ">=2.7.0 <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: ^0.1.3

shared_preferences: ^0.5.0
flushbar: ^1.5.0

# For information on the generic Dart part of this file, see the

# 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:
- assets/images/
# An image asset can refer to one or more resolution-specific "variants", see
# https://flutter.dev/assets-and-images/#resolution-aware.
# For details regarding adding assets from package dependencies, see
# https://flutter.dev/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: persianBold
fonts:
- asset: assets/fonts/main_bold.ttf
- family: persianMedium
fonts:
- asset: assets/fonts/main_medium.ttf
# For details regarding fonts from package dependencies,
# see https://flutter.dev/custom-fonts/#from-packages
我想这个问题可能是针对flutter_datetime_picker: ^1.3.8。但我不确定。
请指导我解决这个问题。谢谢

编辑：
或者问题出在:path_provider:verifyReleaseResources
我在这个方法中的 db_helper 中使用了 path_provider：
initDb() async {
io.Directory documentDirectory = await getApplicationDocumentsDirectory();
String path = join(documentDirectory.path, DB_NAME);
var db = await openDatabase(path, version: 1, onCreate: _onCreate);
return db;
}
path_provider 是否有问题？
编辑编号 2： 更新 pubspec.yaml 后：
cupertino_icons: ^0.1.3
simple_animations: ^1.3.3
sqflite: ^1.1.3
path_provider: ^1.6.10
shared_preferences: ^0.5.0
flushbar: ^1.5.0
flutter_datetime_picker: ^1.3.8
并使用此命令：
flutter build apk --release
我可以毫无问题地构建 APK，但是在 android 设备上安装 APK 时，我只看到一个灰屏，什么都没有。 为什么会这样？
【问题讨论】：
-
你的代码在 git 上更新了吗？因为我没有遇到任何问题。
-
在这里查看你的 git 项目发布版本：gofile.io/d/BXHMJT，它对我来说很好用。 :)
-
谢谢你们的回复。我解决了这个问题。这个问题是因为使用定位在我的小部件树中，并且在删除定位后一切正常。
