Text Overflowing in a Row, Flutter

Try using Expanded widget with flex value set as per the expectation of UI filling.

Sample Code:

Center(
        child: Container(
      height: 80,
      color: Colors.yellow,
      child: Row(
        mainAxisAlignment: MainAxisAlignment.start,
        children: [
          Padding(
            padding: const EdgeInsets.all(8.0),
            child: Icon(Icons.bus_alert),
          ),
          Expanded(
              flex: 1,
              child: Container(
                width: 1,
                color: Colors.green,
                child: Column(
                  children: [Text("Text 1"), Text("Text 1")],
                ),
              )),
          Expanded(
              flex: 3,
              child: Container(
                color: Colors.blue,
                child: Column(
                  mainAxisAlignment: MainAxisAlignment.spaceAround,
                  children: [
                    Text("1 World Way, Los Angeles, CA 90045, USA"),
                    Text("FLIGHT 3231"),
                  ],
                ),
              ))
        ],
      ),
    ))

Note: There is a limitation for the text content using. We need to make sure to set the height according to the expected text length.

Card(
        shape: RoundedRectangleBorder(
