as [Any?] here is actually not a "cast", but a "type annotation". An equivalent fix can be:

let arg: [Any?] = [nil]
let inputEncoded = binaryMessenger.codec.encode(arg)

Fixes

heterogeneous collection literal could only be inferred to '[Any?]'; add explicit type annotation if this is intentional

Which was introduced in #3889 and later got reverted.

See flutter/flutter#126006 for more details about some interesting research on this warning.
