Debug symbols provide information that Sentry displays on the Issue Details page to help you triage an issue. We offer a range of methods to provide Sentry with debug symbols.
With default settings, complete stack traces are available in your Dart error, out of the box, unless you use
obfuscate. In those cases, you need to upload the debug information files generated by the
flutter build, so Sentry can show you proper stack traces.
Errors raised from the native layer in Flutter apps require certain debug information files to be uploaded. For example, an Android app can use
proguard for minification and obfuscation. And when using NDK, dwarf debug files need to be uploaded. Flutter Web requires sourcemaps and iOS apps also require dwarf debug information files.
Sentry requires a dSYM upload to symbolicate your crash logs. The symbolication process unscrambles Apple’s crash logs to reveal the function, file names, and line numbers of the crash. Learn how to upload the dSYM files.
Sentry's Flutter SDK doesn't currently support the
uploadNativeSymbols flag from the Sentry Gradle Plugin.
You can also use our CLI to upload source maps for Flutter Web.
