flutter button with icon and text

TextButton.icon(
            icon: Icon(Icons.camera),
            label: Text('Take A Photo'),
            onPressed: () {},
          )

Flutter has WidgetSpan() to add a widget inside the RichText().

Example use:

RichText(
  text: TextSpan(
    children: [
      TextSpan(
        text: "Click ",
      ),
      WidgetSpan(
        child: Icon(Icons.add, size: 14),
      ),
      TextSpan(
        text: " to add",
      ),
    ],
  ),
)

Above code will produce:

Click + to add

You can treat the child of WidgetSpan like the usual widget.

IconButton(
            icon: Icon(
              Icons.directions_transit,
            ),
            onPressed: () {},
          ),

FlatButton.icon(onPressed: null, icon: null, label: null);
RaisedButton.icon(onPressed: null, icon: null, label: null);
