Methods

asUint8List([int offset = 0, int? length]) → Uint8List
Returns this instance as a Uint8List. Returns the internal bytes buffer if the length and capacity is the same, otherwise creates a copy with the exact length.

Calls the function output with the internal bytes of this instance.
close() → void
Closes bytesIO.
compact() → bool
Compact the internal bytes capacity to length.
flush() → void
Flushes bytesIO data.
indexOf(int byte, [int offset = 0, int? length]) → int
Returns the index of byte inf offset and length range.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
