Flutterを見て、FlutterプラグインをAndroid Studio 3.0.1にインストールしてから、Android Studioを再起動して、Flutterのドキュメントに従って単純なhello worldアプリケーションを作成しました。FlutterがAndroid SDKビルドツールを認識しない25.0.3
Flutter SDKもC:\flutterにインストールされています。そのため、アプリケーション作成プロセスでSDKの場所が正しく選択されました。
しかし、（エミュレータ上）アプリを実行している、

In its third form, all installed and available packages are printed out.
Common Arguments:
--sdk_root=<sdkRootPath>: Use the specified SDK root instead of the SDK containing this tool
--channel=<channelId>: Include packages in channels up to <channelId>.
Common channels are:
0 (Stable), 1 (Beta), 2 (Dev), and 3 (Canary).
--include_obsolete: With --list, show obsolete packages in the
package listing. With --update, update obsolete

フラッターにはこの時点でバグがたくさんありますが、このアルファ段階で時間を過ごす価値があるかどうかはわかりませんが、わかるように、いくつかの円形の問題がありますコマンドですが、コマンドは存在します。私は正確なインストール手順に従いました。それを理解するのに数日かかる場合でも解決策はありませんが、準備ができていなくても結構です。
ありがとう、私はちょうどそれを試み、すべてのライセンスを受け入れ、Androidスタジオとエミュレータを再起動し、上記の投稿に記載されているのと同じ問題がある – pixel
