Fluttertoast.showToast(
  msg: "This is Center Short Toast",
  toastLength: Toast.LENGTH_SHORT,
  gravity: ToastGravity.CENTER,
  timeInSecForIosWeb: 1,
  backgroundColor: Colors.red,
  textColor: Colors.white,
  fontSize: 16.0
);

Build Context 있는 상태

FToast fToast;

@override
void initState() {
    super.initState();
    fToast = FToast();
    fToast.init(context);
}

_showToast() {
    Widget toast = Container(
        padding: const EdgeInsets.symmetric(horizontal: 24.0, vertical: 12.0),
        decoration: BoxDecoration(
        borderRadius: BorderRadius.circular(25.0),
        color: Colors.greenAccent,
        ),
        child: Row(
        mainAxisSize: MainAxisSize.min,
        children: [
            Icon(Icons.check),
            SizedBox(
            width: 12.0,
            ),
            Text("This is a Custom Toast"),
        ],
        ),
    );


    fToast.showToast(
        child: toast,
        gravity: ToastGravity.BOTTOM,
        toastDuration: Duration(seconds: 2),
    );
    
    // Custom Toast Position
    fToast.showToast(
        child: toast,
        toastDuration: Duration(seconds: 2),
        positionedToastBuilder: (context, child) {
          return Positioned(
            child: child,
            top: 16.0,
            left: 16.0,
          );
        });
