This table describe which features of the VM service protocol are available in different modes of the Dart VM. In general, the JIT supports the full set of features, and AOT supports features that do not require code generation or modification. When attempting to use a feature in a mode where it is not supported, the service RPC will return error code 100 ("Feature is disabled").
