[英]I'm new to flutter and I always get error when I tried to run my first project on my physical device
[英]When I connect Firebase to my Flutter project, I get an error
您好,我想将 Firebase 连接到我的 flutter 应用程序。 当我编写代码时,出现错误。
第 29 行第 3 列错误:应为“:”。 ╷ 29 │ # 下面将 Cupertino Icons 字体添加到您的应用程序中。 │ ^ ╵ 请更正 pubspec.yaml 文件 C:\Users\kludi\AndroidStudioProjects\flutter_app_sportkludik\pubspec.yaml
dependencies:

@xkxeeshankhan 是对的。 pubspec.yaml 文件中的空格很重要。 定义 firebase_core package 时请小心。还有一件事,您不应该使用 (") 字符。它应该如下所示:
dependencies:
flutter:
sdk: flutter
firebase_core: ^0.5.2
并且以下命令不会出现在 pubspec.yaml 文件中。 您将在您的终端上运行它。
flutter pub get

# 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

# 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.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
#
# For details regarding fonts from package dependencies,
# see https://flutter.dev/custom-fonts/#from-packages
