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
