@interface FlutterStandardReader : NSObject
A reader of the Flutter standard binary encoding.
See FlutterStandardMessageCodec
for details on the encoding.
The encoding is extensible via subclasses overriding readValueOfType
.

Create a new
FlutterStandardReader
who reads from \p data.Declaration
Objective-C
- (nonnull instancetype)initWithData:(nonnull NSData *)data;

Returns YES when the reader hasn’t reached the end of its data.

Reads a byte value and increments the position.
Declaration
Objective-C
- (UInt8)readByte;
-
Reads a sequence of byte values of \p length and increments the position.
Declaration
