Root Cause

Bang operator (!) used on null value.

generic

Workarounds

  1. 92% success Handle null explicitly: use ?? default or if-null check
  2. 88% success Trace null source: check async operations and API responses

Dead Ends

Common approaches that don't work:

  1. Add ! operator to suppress all nullable warnings 88% fail

    Runtime crashes instead of compile errors

  2. Make all types non-nullable 72% fail

    Forces unnecessary defaults
