Version

9.7.0

Steps to Reproduce

1. Create or run a Flutter app with Sentry Flutter SDK integrated.
2. Enable loadContextsIntegration (default behavior).
3. Run the app on a physical device.
4. Observe the Sentry logs in the console.

(Device: One Plus 8 Pro, Android 13)

Expected Result

Sentry should successfully load and merge device contexts without type errors.
The app should start normally, and events or transactions should be captured and sent to Sentry even if numeric context values (e.g. screen_density, battery_level) are integers in JSON.

Actual Result

When initializing Sentry Flutter SDK, the following error occurs during context loading:

[sentry] [error] loadContextsIntegration failed
type 'int' is not a subtype of type 'double?'
#0 new SentryDevice.fromJson (package:sentry/src/protocol/sentry_device.dart:199:26)
#1 new Contexts.fromJson (package:sentry/src/protocol/contexts.dart:44:26)
#2 _mergeNativeWithLocalContexts (package:sentry_flutter/src/integrations/load_contexts_integration.dart:267:37)
#3 _LoadContextsIntegrationEventProcessor.apply (package:sentry_flutter/src/integrations/load_contexts_integration.dart:120:7)
