https://docs.flutter.dev/get-started/install/macos を読んでいる。

とりあえず適当にDLして、ドキュメント通りに解凍。

➜  hello-flutter git:(master) unzip ~/Downloads/flutter_macos_arm64_3.13.6-stable.zip

適当にディレクトリつくってそこに置いてパスを通す。

➜  hello-flutter git:(master) mkdir -p ~/.flutter
➜  hello-flutter git:(master) mv flutter ~/.flutter

.zshrc あたりに以下を追加。

export PATH="$PATH:$HOME/.flutter/flutter/bin"

とりあえずコマンドインストールはできた。

➜  hello-flutter git:(master) flutter doctor

! Doctor found issues in 3 categories.
The Flutter CLI developer tool uses Google Analytics to report usage and diagnostic data
along with package dependencies, and crash reporting to send basic crash reports.
This data is used to help improve the Dart platform, Flutter framework, and related tools.

Telemetry is not sent on the very first run.
To disable reporting of telemetry, run this terminal command:

flutter --disable-telemetry.
If you opt out of telemetry, an opt-out event will be sent,
and then no further information will be sent.
This data is collected in accordance with the
Google Privacy Policy (https://policies.google.com/privacy).

足りないもんがあるぞと言われたので各ツールは入れておくか。

flutter --disable-telemetry はお好みで。まぁそのままでもいいんじゃまいか。
