Add Long-Running Envelope Worker Isolate for Android, iOS, macOS #3166
Description
Description
Summary
Create a single long-lived Dart isolate to process Sentry envelopes -> offloads sending envelopes from the main isolate
Requirements
- FFI / JNI is already used for
captureEnvelope - Auto-spawn on init
- Enabled by default but can be disabled by a flag (disabled means default behaviour as it is now - sending in main isolate)
- Message transfer via TransferrableTypedData or we transfer the serialized envelope and do the byte conversion within the isolate
Notes
- Need to benchmark to make sure the performance gain is still worth it for small envelopes - if sending small envelopes in the main isolate is still faster then we'll only use the isolate for envelopes bigger than a certain size
