I'd like to re-create this layout but I really can't find a working combination of widget:

I have a Scaffold (black) and inside the body I have to put the red and blue widgets. Can't use bottomSheet because I need to pass variables between red and blue, so everything has to be done inside Scaffold body.

You can test this snippet

class TestApp extends StatelessWidget {
  const TestApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text("AppBar"),
      ),
      body: Column(
        children: [
          Expanded(
            child: ListView.builder(
              itemBuilder: (context, index) {
                return ListTile(
                  tileColor: index.isEven ? Colors.green : Colors.amber,
                );
              },
            ),
          ),
          Container(
            height: 100,
            alignment: Alignment.center,
            width: double.infinity,
            color: Colors.red,
            child: Text("fixed"),
          ),
        ],
      ),
      bottomNavigationBar: BottomNavigationBar(
        items: [
          BottomNavigationBarItem(icon: Icon(Icons.abc), label: ""),
          BottomNavigationBarItem(icon: Icon(Icons.abc), label: "")
        ],
      ),
    );
  }
}

With forloop body, make sure to handle scrollable

body: Column(
  children: [
    Expanded(
        child: Column(
      children: [
        for (int index = 0; index < 4; index  )
          ListTile(
            tileColor: index.isEven ? Colors.green : Colors.amber,
          )
      ],
    )),
    Container(
      height: 100,
      alignment: Alignment.center,
      width: double.infinity,
      color: Colors.red,
      child: Text("fixed"),
    ),
  ],
),
