StandardMessageCodec class

MessageCodec using the Flutter standard binary encoding.

Supported messages are acyclic values of these forms:

Decoded values will use List<dynamic> and Map<dynamic, dynamic> irrespective of content.

On Android, messages are represented as follows:

null: null
bool: java.lang.Boolean
int: java.lang.Integer for values that are representable using 32-bit two's complement; java.lang.Long otherwise
double: java.lang.Double
String: java.lang.String
Uint8List: byte[]
Int32List: int[]
Int64List: long[]
Float64List: double[]
List: java.util.ArrayList
Map: java.util.HashMap

On iOS, messages are represented as follows:

null: nil
bool: NSNumber numberWithBool:
int: NSNumber numberWithInt: for values that are representable using 32-bit two's complement; NSNumber numberWithLong: otherwise
double: NSNumber numberWithDouble:
String: NSString
Uint8List, Int32List, Int64List, Float64List: FlutterStandardTypedData
List: NSArray
Map: NSDictionary

The codec is extensible by subclasses overriding writeValue and readValueOfType.

Constructors

StandardMessageCodec(): Creates a MessageCodec using the Flutter standard binary encoding.
const

hashCode → int: The hash code for this object. [...]
read-only, inherited
runtimeType → Type: A representation of the runtime type of the object.
read-only, inherited

decodeMessage(ByteData message) → dynamic: Decodes the specified message from binary. [...]
override
encodeMessage(dynamic message) → ByteData: Encodes the specified message in binary. [...]
override
readSize(ReadBuffer buffer) → int: Reads a non-negative int from buffer as written by writeSize. [...]
readValue(ReadBuffer buffer) → dynamic: Reads a value from buffer as written by writeValue. [...]
readValueOfType(int type, ReadBuffer buffer) → dynamic: Reads a value of the indicated type from buffer. [...]
writeSize(WriteBuffer buffer, int value) → void: Writes a non-negative 32-bit integer value to buffer using an expanding 1-5 byte encoding that optimizes for small values. [...]
writeValue(WriteBuffer buffer, dynamic value) → void: Writes value to buffer by first writing a type discriminator byte, then the value itself. [...]
noSuchMethod(Invocation invocation) → dynamic: Invoked when a non-existent method or property is accessed. [...]
inherited
toString() → String: Returns a string representation of this object.
