## Detailed Description

A `FlutterMessageCodec` using the Flutter standard binary encoding.

This codec is guaranteed to be compatible with the corresponding StandardMessageCodec on the Dart side. These parts of the Flutter SDK are evolved synchronously.

Supported messages are acyclic values of these forms:

- `nil` or `NSNull`
- `NSNumber` (including their representation of Boolean values)
- `NSString`
- `FlutterStandardTypedData`
- `NSArray` of supported values
- `NSDictionary` with supported keys and values

On the Dart side, these values are represented as follows:

- `nil` or `NSNull`: null
- `NSNumber`: `bool`, `int`, or `double`, depending on the contained value.
- `NSString`: `String`
- `FlutterStandardTypedData`: `Uint8List`, `Int32List`, `Int64List`, or `Float64List`
- `NSArray`: `List`
- `NSDictionary`: `Map`
