FastBarcodeScannerPlatform class abstract
The interface that implementations of fast_barcode_scanner must implement.
Platform implementations should extend this class rather than implement it as fast_barcode_scanner
does not consider newly added methods to be breaking changes. Extending this class
(using extends
) ensures that the subclass will get the default implementation, while
platform implementations that implements
this interface will be broken by newly added
FastBarcodeScannerPlatform methods.
