I am new to flushbar widget. I build a simple code sample that results on the following compiler errors following some articles and videos on the widget. https://pub.dev/packages/flushbar
Most of the examples depend on the onPressed click event. In my case I need to do some processing before displaying of the flushbar message.
I tried with both versions: flushbar: ^1.10.0 flushbar: ^1.9.1
Could you advise what is run with the code below?
This are the compiler errors:
Running Gradle task 'assembleDebug'... Compiler message: /C:/src/flutter/.pub-cache/hosted/pub.dartlang.org/flushbar-1.10.0/lib/flushbar_route.dart:303:8: Error: The method 'FlushbarRoute.install' has fewer positional arguments than those of overridden method 'OverlayRoute.install'. void install() { ^ /C:/src/flutter/packages/flutter/lib/src/widgets/routes.dart:41:8: Context: This is the overridden method ('install'). void install(OverlayEntry insertionPoint) { ^ /C:/src/flutter/.pub-cache/hosted/pub.dartlang.org/flushbar-1.10.0/lib/flushbar_route.dart:311:18: Error: Too few positional arguments: 1 required, 0 given. super.install(); ^ Target kernel_snapshot failed: Exception: Errors during snapshot creation: null build failed.

Here is my sample code. No errors on syntax but fails the compilation.
import 'package:flutter/material.dart';
import 'package:flushbar/flushbar.dart';
class MyHomePage extends StatefulWidget {
MyHomePage();
@override
State<StatefulWidget> createState() {
return _MyHomePage();
}
}
class _MyHomePage extends State<MyHomePage> {
int _selectedIndex = 2;
@override
void initState() {
super.initState();
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: Text('Flushbar')),
body: Center(
child:
BottomNavigationBar(
items: <BottomNavigationBarItem>[
BottomNavigationBarItem(
icon: Icon(Icons.today),
title: Text('Today'), // Today button.
),

title: Text('Finish'), // Finish
),
],
currentIndex: _selectedIndex,
selectedItemColor: Colors.amber[800],
onTap: _onItemTapped,
)
),
);
}
void _onItemTapped(int index) {
setState(() {
switch (index) {
case 0: // Today selected.
// todayButtonPressed();
break;
case 1: // Activity selected.
// activityButtonPressed();
break;
case 2: // Finish selected.
finishButtonPressed();
break;
}
});
}
void finishButtonPressed() async {
// Processing record.
// .....
// ....
displayFlushBar(context);
}
void displayFlushBar(BuildContext context) {
Flushbar(
title: 'Action',
message: 'Is prohibited',
icon: Icon(
Icons.info_outline,

}
