flutter_ota_kit_client 0.1.2

Server-API client for flutter_ota_kit — maps the hot-updater-compatible update-check HTTP contract to a PatchInfo the device SDK can install.

example/lib/main.dart

// flutter_ota_kit_client example
//
// `flutter_ota_kit_client` is a thin Dart server that speaks the
// hot-updater-compatible update-check HTTP contract. The device SDK
// (running on the user's phone) POSTs device fingerprint info to it;
// it queries the configured backend for an update and returns a
// `ServerUpdateResult` that the SDK can install.
//
// Most apps don't run this server themselves — `flutter_ota_kit_cli`
// already does. This example shows the request/response shape if you
// need to wire one up in a custom server (e.g. Dart Frog or shelf).
//
// Run: `dart run example/main.dart`

  // The common case: no update available, device proceeds with the

  // ── 3. The shape when an update is available. ─────────────────────
  // When `isUpToDate=false` and `status=AppUpdateStatus.update`, the
  // device downloads the patch from `patch.artifactUrl`, verifies its
  // MD5 against `patch.fileHash`, and (optionally) verifies the
  // Ed25519 `signature` against your public key.
