dio_refresh 1.2.1

A flutter package for intercepting requests and automatically fetching refresh tokens on API failures

1.2.1

• Fixed a race condition where requests already in flight with an expired token could each trigger a new onRefresh after an earlier refresh had already completed, causing duplicate refresh calls (and 401/503 failures with rotating refresh tokens). Each request now records the access token it was sent with and skips the refresh if the token has already been rotated, retrying directly instead.
• Fixed refresh failures not propagating to concurrent requests: the in-flight refresh now resolves to a success/failure result that every waiting onError handler observes, so a failed refresh is forwarded to all of them instead of retrying with an invalid token.

1.2.0

• Breaking: Removed time-based refresh throttling and the throttleDuration option added in 1.1.0. Upgrade by deleting any throttleDuration argument from your setup.
• Refresh is serialized with an in-flight Future (_refreshFuture): the first failure starts onRefresh; any other concurrent onError handlers await that same future instead of starting another refresh.
• Outgoing requests wait their turn: onRequest awaits _refreshFuture before applying authHeader, so new calls do not attach a stale token while a refresh is still running.
• After the shared refresh completes, _refreshFuture is cleared so a later auth failure can start a new refresh cycle.

1.1.0

• Fixed onRefresh being called multiple times simultaneously, resulting in future API failure
• Added configurable throttleDuration to control token refresh throttling window (default: 800ms)

1.0.8

• Fixed Bad state: handler already called error when token refresh fails — handler was being called twice due to fall-through after the synchronized block

1.0.7

• Added support for providing an OnRefreshFailedCallback to handle refresh failures

1.0.6

• Fix: Refresh is now triggered when either the server requests it (shouldRefresh) or the token is locally expired. Previously both conditions were required, causing refresh to be skipped in revoked-token scenarios

1.0.5

• Added retry interceptors

1.0.4

• Fixed form data being submitted twice error on request retry
• Added custom token validation callback

1.0.3

• Fixed error handling for isRefreshing deadlock
• Fixed onRefresh being called multiple times simultaneously

1.0.2

• Fixed refresh being called even if token is null
• Fixed isRefreshing deadlock, causing APIs to never resolve

1.0.1

• Fixed changelog

1.0.0

• Fixed bulk API call handling to prevent failures.

0.0.1

• Initial release.
