Navigation on flutter on debug in Visual Studio Code

I’m building an application in flutter, I build two pages the main page and a configuration page, after that I added two buttons to the main page, one of then to navigate to the configuration page with this code:

void _gotoConfigurationPage() {
    Navigator.push(context, MaterialPageRoute(builder: (context) {
      return const ConfigurationPage(title: 'ConfigurationPage');
    }));
  }

But when I try to debug the application in an Android emulator or an Android phone, the navigation doesn’t work, and the other buttons stop working, BUT when I open the application in the emulator or on the phone, the navigation works!

Am I doing something wrong?

===EDIT===

This is the code of the button in the main page used to navitate to the configuration page.

floatingActionButton: Row(
        mainAxisAlignment: MainAxisAlignment.spaceEvenly,
        children: [
          FloatingActionButton(
            onPressed: _gotoConfigurationPage,
            tooltip: 'Configuration',
            child: const Icon(Icons.settings),
          ),
          FloatingActionButton(
            onPressed: _action2,
            tooltip: 'Action2',
            child: const Icon(Icons.settings),
          ),
        ],
      ),
