I have developed a flutter app for Android that shows a button in the bottom of the screen.

This is how I placed the widgets.

return Scaffold(
      appBar: AppBar(title: Text(widget.title)),
      body: FutureBuilder<void>(
        future: _initializeControllerFuture,
        builder: (context, snapshot) {
          if (snapshot.connectionState == ConnectionState.done) {
            return Column(
              children: [
                Expanded(child: CameraPreview(_controller)),
                Padding(
                  padding: const EdgeInsets.only(
                    bottom: 0,
                    left: 5.0,
                    right: 5.0,
                  ),
                  child: SizedBox(
                    width: double.infinity, // Occupies full available width
                    child: ElevatedButton(
                      onPressed: _isButtonEnabled
                          ? () async {
                              // Mark the anonymous function as async
                              await _generateAttendance(context);
                            }
                          : null,
                      style: ElevatedButton.styleFrom(
                        elevation: 20.0,
                        shadowColor: Colors.black,
                        backgroundColor: btnColor, // Set the background color
                        foregroundColor: Colors.white, // Set the text color
                        shape: RoundedRectangleBorder(
                          borderRadius: BorderRadius.circular(
                            8.0,
                          ), // Set the border radius/ Rectangular border
                        ),
                      ),
                      child: Text('Registrar $tipo'),
                    ),
                  ),
                ),
              ],
            );
          } else {
            return Center(child: CircularProgressIndicator());
          }
        },
      ),
      floatingActionButton: Padding(
        padding: const EdgeInsets.only(bottom: 50.0),
        child: FloatingActionButton(
          onPressed: () async {
            await _takePicture(context);
          },
          child: Icon(Icons.camera_alt),
        ),
      ),
    );

When I test it in a real phone, the ´ElevatedButton´ appears underneath the Android navigation buttons, this way:

Hwo can I solve it?

Thanks
