Sentry's Flutter SDK enables automatic reporting of errors and exceptions, and identifies performance issues in your application. The below, is a list of features that are available as part of this SDK.

Features:

• Under the hood the SDK relies on Sentry's Dart SDK:
  • The minimum required version is 2.17.0 and Flutter SDK version is 3.0.0.
  • This SDK includes all the Features of Sentry's Dart SDK.
• Automatic native crash error tracking (using both Android and iOS), including:
  • Java, Kotlin, C, and C++ code for Android.
  • ObjC, Swift, and C for iOS.
• Automatic detection of Application Not Responding (ANR) on Android and App Hangs on iOS.
• Offline storage of events.
• Events enriched with device data.
• Breadcrumbs automatically captured:
  • by the Flutter SDK.
  • via the Native SDKs Automatic Breadcrumbs for Android and Automatic Breadcrumbs for iOS.
  • as well as http with the Dart SDK.
• Integrations for sqflite, routing and more. For a complete list, see integrations.
• Release Health tracks crash free users and sessions.

• Source Context shows snippets of code around the location of stack frames.

Web Limitations:

Sentry supports Flutter Web as well, with the following limitations:

• Issue titles are not human-readable, as they show the minified name.
• Stack traces aren't symbolicated when compiled using WebAssembly (WASM).
• Stack traces are not symbolicated when loaded as a browser extension.
• Offline caching isn't supported for exceptions.
• Release Health isn't supported.
• Device context data isn't as rich on the web as it is on mobile.

Desktop Limitations:

Sentry supports Flutter on Linux and Windows as well, with the following limitations:

• Native crashes are not supported on Windows.
• Release Health isn't supported.
• Device context data isn't as rich on Linux and Windows as it is on mobile.

When running on macOS, you can expect the same feature set as on iOS.
