writeSync method
Writes p.byteLength bytes from p to the underlying data
stream. It returns the number of bytes written from p (0 <= n
<= p.byteLength) and any error encountered that caused the write to
stop early. writeSync() must throw a non-null error if it returns n <
p.byteLength. writeSync() must not modify the slice data, even
temporarily.
Implementations should not retain a reference to p.
Implementation
_i2.num writeSync(_i9.Uint8List p) => _i3.callMethod(
this,
'writeSync',
[p],
