Answer 1

You can use the ClipRRect widget:

Scaffold(
      body: Padding(
        padding: EdgeInsets.all(8.0),
        child: Row(
          children: [
            ClipRRect(
              borderRadius: BorderRadius.circular(20),
              child: Container(
                width: 100,
                color: Colors.red,
                child: Text(
                  'Healthy',
                  textAlign: TextAlign.center,
                  style: TextStyle(color: Colors.white),
                ),
              ),
            ),
            SizedBox(
              width: 10,
            ),
            ClipRRect(
              borderRadius: BorderRadius.circular(20),
              child: Container(
                width: 100,
                color: Colors.red,
                child: Text(
                  'Healthy',
                  textAlign: TextAlign.center,
                  style: TextStyle(color: Colors.white),
                ),
              ),
            ),
          ],
        ),
      ),
    );
