   We could also unit-test them for added assurance (e.g., have a test that asserts that the address of the first member plus the size of the struct is the same as the address of the expected last member plus the size of that member).

   We could also unit-test them for added assurance (e.g., have a test that asserts that the address of the first member plus the size of the struct is the same as the address of the expected last member plus the size of that member).

   This bit was added by:

   1. [Embedder API] Freeze parts of API for ABI stability flutter-team-archive/engine#39963
   2. [Embedder API] Lock nested structs for ABI stability flutter-team-archive/engine#40069

   I'll leave this open as we should do a pass to verify all sealed structs are documented.
