1

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.
  • Attachments that can enrich your event by storing additional files, such as config or log files.
  • Tracing that can track:
    • App start time.
    • Time to Initial Display and Time to Full Display.
    • Slow and Frozen Frames.
    • User Interaction which include clicks, long clicks, taps and so on.
    • For a complete list see automatic instrumentations.
  • User Feedback, providing the ability to collect user feedback when an unexpected event occurs.
  • Screenshot and View Hierarchy attachments for errors.
  • Profiling collects detailed information about your code at the function level.
    • Profiling is currently supported on iOS and macOS.
    • It captures profiles across multiple language layers, including native languages (such as Swift and Objective-C) as well as Dart.
  • Source Context shows snippets of code around the location of stack frames.
  • Sentry Dart Plugin makes uploading debug symbols easy and automatic.

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.
