  }
}

class DemoPage extends StatefulWidget {

      appBar: AppBar(title: const Text('Nextgen Showcase')),
      body: Center(
        child: ElevatedButton(

          onPressed: () {
            _controller.setSteps(<ShowcaseStep>[
              ShowcaseStep(
                key: _buttonKey,
                title: 'Primary action',
                description: 'Tap here to perform the main action.',
              ),
            ]);
            _controller.start(context);
          },
          child: const Text('Showcase me'),
