您可以通過將相應的匯入陳述句添加到 DartPad 代碼的頂部來簡單地匯入它們。下面是一個例子GoogleFonts：
import 'package:flutter/material.dart';
// simply add this line to import GoogleFonts
import 'package:google_fonts/google_fonts.dart';
const 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 Text(
'This is Google Fonts',
// Use the package wherever you like
style: GoogleFonts.lato(
textStyle: TextStyle(color: Colors.blue, letterSpacing: .5),
),
);
}
}
