TypeMirror reflectType(
Type key
)

This function returns a TypeMirror reflecting the type represented by key.

If key is not an instance of Type then this function throws an ArgumentError.

Note that since one cannot obtain a Type object from another isolate, this function can only be used to obtain type mirrors on types of the current isolate.
