# 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.

# To add assets to your application, add an assets section, like this:
assets:
- assets/flutter.pdf
# - images/a_dot_ham.jpeg
# 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: 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

描述:一个新的颤振项目。
#以下行可防止将包意外发布到
#pub.dev使用“pub publish”。这是私人软件包的首选。
发布到:“无”#如果要发布到pub.dev,请删除此行
#下面定义了应用程序的版本和内部版本号。
#版本号是由点分隔的三个数字,如1.2.43
#后跟可选的内部版本号,以+分隔。
#版本和制造商编号都可能在颤振中被覆盖
#通过分别指定--build name和--build number来生成。
#在Android中,版本名用作版本名,而版本号用作版本代码。
#更多关于Android版本控制的信息,请访问https://developer.android.com/studio/publish/versioning
#在iOS中,生成名称用作CbundleShortVersionString,而生成编号用作CbundLeverVersion。

能否请您共享获取错误的代码?并共享您的pubspec.yaml导入的依赖项。我在main的第一行获取错误。dart@Deepika你找到解决方案了吗?运行flutter clean并重新启动应用程序对我来说很有效。你能分享你收到错误的代码吗?和sha您的pubspec.yaml也导入了依赖项。我在main的第一行中得到了错误。dart@Deepika你找到解决方案了吗?运行flutter clean并重新启动应用程序对我很有效。非常感谢!我的应用程序只会在发布版本中抛出错误,这让我非常恼火!非常感谢!我的应用程序只会抛出错误在发布版本上,这让我抓狂!
