# Manual Upload | Sentry for Flutter

If you choose not to use the Sentry Dart Plugin, you can manually upload debug symbols for your Flutter applications. This page provides instructions for different platforms.

## [iOS and macOS](https://docs.sentry.io/platforms/dart/guides/flutter/debug-symbols/manual-upload.md#ios-and-macos)

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.

## [Android](https://docs.sentry.io/platforms/dart/guides/flutter/debug-symbols/manual-upload.md#android)

For Android applications, you need to upload mapping files manually with the Sentry CLI.

## [Android NDK](https://docs.sentry.io/platforms/dart/guides/flutter/debug-symbols/manual-upload.md#android-ndk)

For native code crashes in Android applications, you need to upload ELF DWARF debug files.

If you're using a version of `sentry_flutter` earlier than 5.1, native symbolication on Android requires a specific configuration. Refer to [Troubleshooting](https://docs.sentry.io/platforms/dart/guides/flutter/troubleshooting.md#native-symbolication-on-android) for more information.

Sentry's Flutter SDK doesn't currently support the `uploadNativeSymbols` flag from the [Sentry Gradle Plugin](https://docs.sentry.io/platforms/android/configuration/gradle.md).

## [Web](https://docs.sentry.io/platforms/dart/guides/flutter/debug-symbols/manual-upload.md#web)

For web applications, you need to upload source maps to get readable stack traces.
