ones1ght_sdk 0.0.4

OneS1ght indoor positioning SDK for Flutter. Wraps the OneS1ght iOS and Android SDKs: UWB positioning, zone enter / exit / dwell events and upload.

example/lib/main.dart

// OneS1ght Flutter 예제 — 초기화 → 권한 → 층 지정 → 측위 시작 흐름을 버튼으로 하나씩 해 본다.
//
// SDK 키는 코드에 넣지 않고 실행할 때 넘긴다:
//   flutter run --dart-define=ONES1GHT_SDK_KEY=ock_sdk_…
//
// 화면에 보이는 로그는 앱 Documents/ones1ght-example.log 에도 쌓인다 — 릴리스 빌드는 print 가 콘솔로 나오지 않아
// 기기 밖에서 보려면 파일을 꺼내야 한다(README).
