This issue does not seem to have been resolved completely, as building the wasm_release target with the --no-prebuilt-dart-sdk flag does not work. The prebuilt_dart_sdk variable is unconditionally set to true in https://github.com/flutter/engine/pull/36851/files#diff-fed47f409f6a27a39fe7b0e6b3ebbceb645d295259e350614afeb8c0a3eecae2R636

Further work on making the wasm_release target build without a prebuilt Dart SDK is tracked in a new issue #119513 , and this issue can remain closed.
