Detailed Description

A byte buffer holding UInt8, SInt32, SInt64, or Float64 values, used with FlutterStandardMessageCodec and FlutterStandardMethodCodec.

Two's complement encoding is used for signed integers. IEEE754 double-precision representation is used for floats. The platform's native endianness is assumed.

Method Documentation

typedDataWithBytes:

+ (instancetype) typedDataWithBytes:

(NSData*)

data

Creates a FlutterStandardTypedData which interprets the specified data as plain bytes.

Parameters

data	the byte data.

Definition at line 146 of file FlutterStandardCodec.mm.

typedDataWithFloat32:

+ (instancetype) typedDataWithFloat32:

(NSData*)

data

Creates a FlutterStandardTypedData which interprets the specified data as 32-bit floats.

Parameters

data	the byte data. The length must be divisible by 8.

typedDataWithInt32:

+ (instancetype) typedDataWithInt32:

(NSData*)

data

Creates a FlutterStandardTypedData which interprets the specified data as 32-bit signed integers.

Parameters

data	the byte data. The length must be divisible by 4.
