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 is used as CFBundleVersion. # Read more about iOS versioning at # https://developer.apple.com/library/archive/documentation/General/Reference/InfoPlistKeyReference/Articles/CoreFoundationKeys.html # In Windows, build-name is used as the major, minor, and patch parts # of the product and file versions while build-number is used as the build suffix. version: 1.0.0+1 environment: sdk: ">=2.19.0 <3.0.0" # Dependencies specify other packages that your package needs in order to work. # To automatically upgrade your package dependencies to the latest versions # consider running `flutter pub upgrade --major-versions`. Alternatively, # dependencies can be manually updated by changing the version numbers below to # the latest version available on pub.dev. To see which dependencies have newer # versions available, run `flutter pub outdated`. 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: ^1.0.2 dev_dependencies: flutter_test: sdk: flutter # The "flutter_lints" package below contains a set of recommended lints to # encourage good coding practices.
