プログラム（プロジェクト）が多くなってくると、それぞれのプロジェクトでFlutterのバージョンを固定・指定したくなってきます。
FVMを使うとプロジェクトディレクトリごとにFlutterのバージョンを指定できるようです。
また、プロジェクト内にfvmの設定を含めておくと、各個人の環境でそのバージョンのFlutterをインストールできるようになります。
便利ですねー。
FVMのインストール
こちらの公式サイトを参考にインストールしましょう。
Macでのインストール方法はこちら。
brew tap leoafarias/fvm

In order to run your empty application, type:
$ cd .
$ flutter run
Your empty application code is in ./lib/main.dart.パラメータの説明
- リポジトリ名の区切りをハイフンにしたいので、ディレクトリ名もハイフンにする
- fvm flutter create .
ディレクトリ名を指定するが、ディレクトリ内で実行するのでカレントディレクトリを指定する - –project-name sample_app
パッケージ名にハイフンを利用できないため、アンダーバー区切りで指定する - –org com.sampleapp
任意のドメイン名を指定する - -e
