  @override
  Widget build(BuildContext context) {
    return Stack(
      children: [
        ScannerPreview(
          controller: _scannerController,
        ),
        Align(
          alignment: Alignment.bottomCenter,
          child: SafeArea(
            child: FloatingActionButton(
              child: const Icon(Icons.camera),
              onPressed: () async {
                final image = await _scannerController.takeAndProcess();
                if (!context.mounted) return;

                Scaffold.of(context).showBottomSheet(
                  (context) {
                    return SafeArea(
                      child: Padding(
                        padding: const EdgeInsets.all(20),
                        child: Image(
                          image: image,
                          fit: BoxFit.fitWidth,
                        ),
                      ),
                    );
                  },
                );
              },
            ),
          ),
        )
      ],
    );
  }
}

ToDo:

• Lock focus on document.
• Color/gamma enchantments.
• Better perspective correction using camera lens info.
