我正在尝试创建一个新的Flutter项目。我尝试了以下两种方法:
1. flutter create
flutter create --org com.domain.appname
它们都返回了以下内容:
No option specified for the output directory.
Create a new Flutter project.
If run on a project that already exists, this will repair the project,
recreating any files that are missing.
Global options:
-h, --help Print this usage information.
-v, --verbose Noisy logging, including all shell commands
executed.
If used with "--help", shows hidden options. If used
with "flutter doctor", shows additional diagnostic
information. (Use "-vv" to force verbose logging in
those cases.)
-d, --device-id Target device id or name (prefixes allowed).
--version Reports the version of this tool.
--suppress-analytics Suppress analytics reporting when this command runs.
Usage: flutter create <output directory>
-h, --help Print this usage information.
--[no-]pub Whether to run "flutter pub get" after the project
has been created.
(defaults to on)
--[no-]offline When "flutter pub get" is run by the create
command, this indicates whether to run it in
offline mode or not. In offline mode, it will need
to have all dependencies already available in the
pub cache to succeed.
--[no-]overwrite When performing operations, overwrite existing
files.
--description The description to use for your new Flutter
project. This string ends up in the pubspec.yaml
file.
(defaults to "A new Flutter project.")
--org The organization responsible for your new Flutter
project, in reverse domain name notation. This
string is used in Java package names and as prefix
in the iOS bundle identifier.
(defaults to "com.example")
--project-name The project name for this new Flutter project. This
must be a valid dart package name.
-i, --ios-language The language to use for iOS-specific code, either
ObjectiveC (legacy) or Swift (recommended).
[objc, swift (default)]
-a, --android-language The language to use for Android-specific code,
either Java (legacy) or Kotlin (recommended).
[java, kotlin (default)]
--platforms The platforms supported by this project. Platform
folders (e.g. android/) will be generated in the
target project. This argument only works when
"--template" is set to app or plugin. When adding
platforms to a plugin project, the pubspec.yaml
will be updated with the requested platform. Adding
desktop platforms requires the corresponding
desktop config setting to be enabled.
[ios (default), android (default), windows
(default), linux (default), macos (default), web
(default)]
-t, --template=<type> Specify the type of project to create.
[app] (default) Generate a Flutter application.
[module] Generate a project to add a Flutter module to an
existing Android or iOS application.
[package] Generate a shareable Flutter project containing
only Dart code.
[plugin] Generate a shareable Flutter project containing an
API in Dart code with a platform-specific
implementation for Android, for iOS code, or for
both.
-s, --sample=<id> Specifies the Flutter code sample to use as the
"main.dart" for an application. Implies
"--template=app". The value should be the sample ID
of the desired sample from the API documentation
website (http://docs.flutter.dev/). An example can
be found at:
https://api.flutter.dev/flutter/widgets/SingleChild
ScrollView-class.html
--list-samples=<path> Specifies a JSON output file for a listing of
Flutter code samples that can be created with
"--sample".
Run "flutter help" to see global options.
以下是我的
flutter doctor
