Powered by the Dart language, Flutter is one of the fastest-growing cross-platform programming frameworks in the world. Since its release in 2017 it has been empowering developers to build mobile apps that work seamlessly across iOS and Android with a single code-base. If you’re a Flutter developer, you’ll already know the importance of building better quality software, faster – after all, it was made for that very reason.

That’s why today, Raygun is proud to bring you Flutter support Crash Reporting. This highly requested release gives you complete visibility into the health of your Flutter applications, with rich diagnostics that take you to the root cause of errors and crashes.

Flutter for Raygun works across both mobile, web, and desktop applications. You can see the latest compatibility by visiting the raygun4flutter package on

Errors over time graph

Build an unbeatable issue resolution workflow

Raygun helps you build a world-class development workflow to detect, diagnose, and resolve issues quickly. Keep a watchful eye over the health of your entire tech-stack, monitor deployments into production in real-time, and prioritize the most high-impact fixes.

Get to the root cause of issues faster

Stop relying on log files or support tickets with incomplete information. Drill into problematic errors to see the full stack trace along with the contextual information needed to build a clear picture of precisely how and why an error occurred.

Then, take it a step deeper by connecting to source code repositories using native integrations with GitHub, Azure DevOps, and Bitbucket that take you to the exact line of code causing the error, directly in Raygun.

Prioritize issues for the biggest impact

Raygun intelligently groups errors by root cause so that team members can see a manageable list of bugs to fix. Order and prioritize errors based on users affected and the number of occurrences. Prioritizing errors based on the number of users affected ensures that optimizations are having the greatest positive impact on the largest number of users.

By using top-level filters, you can segment errors by date, version, host, OS, browser, machine name, and custom tags, to focus on what matters most to your business. Attach custom data to error reports for even greater context and control.


Getting set up with Flutter Crash Reporting is easy – simply follow the steps outlined below or visit the setup documentation for the most up-to-date instructions.
