Install
Add another_flushbar v2 to your pubspec. Already using it? Just upgrade.
Connect
Call FlushbarRemote.init() once. The SDK opens a persistent SSE connection.
Notify
POST to /v1/notify from any backend, cron job, or our dashboard.
Everything you need to notify your users.
Real-time delivery
SSE-based transport, sub-100 ms latency, automatic reconnect with exponential backoff.
Full Flushbar control
Title, message, color, duration, position, icon — every property is remote-controllable.
REST API + Dashboard
Send from anywhere, in any language. Curl it, cron it, or trigger from our web UI.
Zero rebuilds
Change copy, theme and behavior without shipping a new build to the App Store.
Delivery analytics
Track connected clients, delivered counts, and per-event acknowledgements in real time.
Multi-project
One account, many apps. Isolated API keys, separate quotas, independent dashboards.
Two lines
of code.
That's all your app needs. Drop the SDK in once and forget about it — we handle reconnects, retries, and platform quirks.
- Persistent SSE connection managed automatically
- Exponential backoff with jitter on reconnect
- Works on Android, iOS, Web and Desktop
