Two tools, one SDK: structured Logs from your app in production and Session Replay with screenshots and taps of every user's real journey.
Install the package from pub.dev, paste your project token, and the data starts arriving in your dashboard on its own. No agents, no strange setup.
Continuous, lightweight telemetry so you know how your app is doing. You emit logs from your code and query them in the dashboard: filters, search, stack traces, and volume per hour.

await FlogLogs.init(

Attach a capture of the screen at the moment of the error with screenshot: true.
Per-log and global attributes (e.g. userId after login). In the dashboard: filters by level, logname, and text.
Batches every 10 s, flush when going to background, and retry on the next launch if there was no network.
Record screens, numbered taps, scrolls, navigation, and errors, and play it back step by step in the web viewer. Ideal for reproducing that bug that "only happens to one user" and for understanding real UX.
Wireflow of the journey + playback with a timeline: navigation, taps, network, logs, and errors in order.
Message, stack trace, and a screenshot of the instant it failed — plus everything the user did before.
On going to background, on close, or on a crash. It only uploads if there's new content.
