+/// an optional parameter.
+///
+/// It signifies that the export, member or parameter was *added* in
+/// that version.
+///
+/// When applied to a library declaration, it also a applies to
+/// all members declared or exported by that library.
+/// If applied to a class, it also applies to all members and constructors
+/// of that class.
+/// If applied to a class method, or parameter of such,
+/// any method implementing that interface method is also annotated.
+/// I multiple `Since` annotations apply to the same declaration or
+/// parameter, the latest version takes precendence.
+///
+/// Any use of a marked API may trigger a warning if the using code
+/// does not require an SDK version guaranteeing that the API is available,
+/// unless the API feature is also provided by something else.
+/// It is only a problem if an annotated feature is used, and the annotated
+/// API is the *only* thing providing the functionality.
+/// For example, using `Future` exported by `dart:core` is not a problem
+/// if the same library also imports `dart:async`, and using an optional
+/// parameter on an interface is not a problem if the same type also
+/// implements another interface providing the same parameter.
+///
+/// The version must be a semantic version (like `1.4.2` or `0.9.4-rec.4`),
+/// or the first two numbers of a semantic version (like `1.0` or `2.2`),
+/// representing a stable release, and equivalent to the semantic version
+/// you get by appending a `.0`.
