You need to provide child and onPressed parameter in order to render the widget, else it won't render, which results in non working UI.

Check out the code i modified :

import 'package:flutter/material.dart';

final Color darkBlue = Color.fromARGB(255, 18, 32, 47);

void main() {

runApp(MyApp());

}

class MyApp extends StatelessWidget {

@override

Widget build(BuildContext context) {

return MaterialApp(

theme: ThemeData.dark().copyWith(scaffoldBackgroundColor: darkBlue),

debugShowCheckedModeBanner: false,

home: Scaffold(

body: Center(

child: MyWidget(),

),

),

);

}

}

class MyWidget extends StatelessWidget {

@override

Widget build(BuildContext context) {

return MaterialApp(

home: SafeArea(

child: Scaffold(

body: Column(

crossAxisAlignment: CrossAxisAlignment.stretch,

children: [

FlatButton(

color: Colors.red,

onPressed:()=>printData(),

child: Text("click"),

),

FlatButton(

color: Colors.green,

onPressed:()=>printData(),

child: Text("click"),

),

FlatButton(

color: Colors.blue,

onPressed:()=>printData(),

child: Text("click"),

),

],

),

),

));

}

}

void printData(){

print('Hello');

}
