initialize method

Future<void> initialize({ bool checkPermission = true, Duration timeout = const Duration(seconds: 60), })

Initialization.

Location information is available or not and permissions are granted.

If checkPermission is true, permission check is performed.

初期化を行います。

位置情報が利用可能かどうかとパーミッションの許可を行います。

checkPermissionがtrueの場合、パーミッションチェックを行います。
