我正在尝试减少此处输入图像描述之间的空间，即注释图像和注释标题的前导和标题
我的部分代码是：
drawer: Drawer(
child: ListView(
padding: EdgeInsets.zero,
children: [
Container(
height: 110,
child: DrawerHeader(
child: Text(
'My Secret Diary',
style: TextStyle(
fontSize: 35,
fontWeight: FontWeight.bold,
fontFamily: 'madelyn'),
),
decoration: BoxDecoration(
color: Colors.greenAccent,
),
),
),
Container(
//decoration : BoxDecoration( border: Border.all(color: Colors.black, width: 1)),
child: ListTile(
selectedTileColor: Colors.blue,
leading: Image.asset('assets/images/notes.png' , width: 25, height: 25, fit: BoxFit.cover,),
title: Text(
'Notes',
style: TextStyle(fontFamily: 'alkes', fontSize: 18),
),
),
)
],
),
),
整个代码：
import 'package:flutter/material.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
// This widget is the root of your application.
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
// This is the theme of your application.
//
// Try running your application with "flutter run". You'll see the
// application has a blue toolbar. Then, without quitting the app, try
// changing the primarySwatch below to Colors.green and then invoke
// "hot reload" (press "r" in the console where you ran "flutter run",
// or simply save your changes to "hot reload" in a Flutter IDE).
// Notice that the counter didn't reset back to zero; the application
// is not restarted.
primarySwatch: Colors.blue,
// This makes the visual density adapt to the platform that you run
// the app on. For desktop platforms, the controls will be smaller and
// closer together (more dense) than on mobile platforms.
visualDensity: VisualDensity.adaptivePlatformDensity,
),
home: MyHomePage(title: 'Notes'),
);
}
}
class MyHomePage extends StatelessWidget {
MyHomePage({Key key, this.title}) : super(key: key);
// This widget is the home page of your application. It is stateful, meaning
// that it has a State object (defined below) that contains fields that affect
// how it looks.
// This class is the configuration for the state. It holds the values (in this
// case the title) provided by the parent (in this case the App widget) and
// used by the build method of the State. Fields in a Widget subclass are
// always marked "final".
final String title;
GlobalKey<ScaffoldState> _scaffoldkey = GlobalKey<ScaffoldState>();
