Instant sync and document state in React Native

Every Instant document goes through several states. PSPDFKit Instant provides a number of callbacks from the Instant document state, which are outlined below:

• onSyncStarted — Triggered when a sync operation starts. This can be a sync initiated by the user or triggered automatically by the Instant document.

• onSyncFinished — Triggered when a sync operation completes successfully.

• instantSyncFailed — Triggered when a sync operation fails. It includes an error message explaining the cause of the failure.

• instantAuthenticationFinished — Triggered when the user successfully completes the authentication process for the Instant document.

• instantAuthenticationFailed — Triggered when the user fails to authenticate for the Instant document. It includes an error message explaining the cause of the failure.

• instantDownloadFinished (iOS only) — Triggered when a download operation for the Instant document completes successfully.

• instantDownloadFailed (iOS only) — Triggered when a download operation for the Instant document fails. It includes an error message explaining the cause of the failure.
