flush method

@override Future<void> flush()

Implementation

@override
Future<void> flush() async {
  // The Browser RUM SDK auto-flushes pending data via beforeunload; there is
  // no synchronous flush API exposed through the JS bridge. Tests that need
  // deterministic flushing should rely on UploadFrequency.frequent + a
  // post-flush wait_for poll on the intake.
