macOS 上搭建Flutter開發環境

xnllc發表於2020-10-16

1. 環境

修改環境變數修改檔案 ~/.bash_profile

1. 修改~/.bash_profile檔案
   檔案內容新增：
   export PUB_HOSTED_URL=https://pub.flutter-io.cn
   export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
2. 執行修改 source ~/.bash_profile

下載程式碼 git clone -b stable https://gitee.com/netscript/flutter

安裝本來只是進入bin中想檢視一下flutter版本號，也會先安裝

Building flutter tool...
  ╔════════════════════════════════════════════════════════════════════════════╗
  ║ A new version of Flutter is available!                                     ║
  ║                                                                            ║

  ╚════════════════════════════════════════════════════════════════════════════╝


Manage your Flutter app development.

Common commands:

  flutter create <output directory>
    Create a new Flutter project in the specified directory.

  flutter run [options]
    Run your Flutter application on an attached device or in an emulator.

Usage: flutter <command> [arguments]

Global options:
-h, --help                     Print this usage information.
-v, --verbose                  Noisy logging, including all shell commands executed.
                               If used with --help, shows hidden options.

    --quiet                    Reduce the amount of output from some commands.
    --[no-]wrap                Toggles output word wrapping, regardless of whether or not the output is a
                               terminal.
                               (defaults to on)

    --wrap-column              Sets the output wrap column. If not set, uses the width of the terminal.
                               No wrapping occurs if not writing to a terminal. Use --no-wrap to turn off
                               wrapping when connected to a terminal.

-d, --device-id                Target device id or name (prefixes allowed).
    --version                  Reports the version of this tool.
    --machine                  When used with the --version flag, outputs the information using JSON.
    --[no-]color               Whether to use terminal colors (requires support for ANSI escape
                               sequences).
                               (defaults to on)

    --[no-]version-check       Allow Flutter to check for updates when this command runs.
                               (defaults to on)

    --suppress-analytics       Suppress analytics reporting when this command runs.
    --bug-report               Captures a bug report file to submit to the Flutter team.
                               Contains local paths, device identifiers, and log snippets.

    --packages                 Path to your ".packages" file.
                               (required, since the current directory does not contain a ".packages"
                               file)

    --flutter-root             The root directory of the Flutter repository.
                               Defaults to $FLUTTER_ROOT if set, otherwise uses the parent of the
                               directory that the "flutter" script itself is in.

Local build selection options (not normally required):
    --local-engine-src-path    Path to your engine src directory, if you are building Flutter locally.
                               Defaults to $FLUTTER_ENGINE if set, otherwise defaults to the path given
                               in your pubspec.yaml dependency_overrides for sky_engine, if any, or,
                               failing that, tries to guess at the location based on the value of the
                               --flutter-root option.

    --local-engine             Name of a build output within the engine out directory, if you are
                               building Flutter locally.
                               Use this to select a specific version of the engine if you have built
                               multiple engine targets.
                               This path is relative to --local-engine-src-path/out.

Options for testing the "flutter" tool itself:
    --record-to                Enables recording of process invocations (including stdout and stderr of
                               all such invocations), and file system access (reads and writes).
                               Serializes that recording to a directory with the path specified in this
                               flag. If the directory does not already exist, it will be created.

    --replay-from              Enables mocking of process invocations by replaying their stdout, stderr,
                               and exit code from the specified recording (obtained via --record-to). The
                               path specified in this flag must refer to a directory that holds
                               serialized process invocations structured according to the output of
                               --record-to.

    --show-test-device         List the special 'flutter-tester' device in device listings. This headless
                               device is used to
                               test Flutter tooling.

Available commands:
  analyze                  Analyze the project's Dart code.
  assemble                 Assemble and build flutter resources.
  attach                   Attach to a running application.
  bash-completion          Output command line shell completion setup scripts.
  build                    Flutter build commands.
  channel                  List or switch flutter channels.
  clean                    Delete the build/ and .dart_tool/ directories.

  help                     Display help information for flutter.
  ide-config               Configure the IDE for use in the Flutter tree.
  inject-plugins           Re-generates the GeneratedPluginRegistrants.
  install                  Install a Flutter app on an attached device.
  logs                     Show log output for running Flutter apps.
  make-host-app-editable   Moves host apps from generated directories to non-generated directories so
                           that they can be edited by developers.
  precache                 Populates the Flutter tool's cache of binary artifacts.
  pub                      Commands for managing Flutter packages.
