dataToBufferPointer method
Writes data into the outlet's push buffer and returns the pointer.
Note: for string streams the per-element allocations made here are only released on the next push/cleanup or in destroy; prefer pushSample/pushSampleSync for string data.
Implementation
Pointer<NativeType> dataToBufferPointer(Iterable<dynamic> data) {
_validateSampleData(data);
// Set the sample data in the buffer
_pushFn.listToBuffer(data, _bufferBang);
return _bufferBang;
}
