使用Google Pay flutter软件包here。
import 'package:flutter/material.dart';
import 'dart:async';
import 'package:flutter/services.dart';
import 'package:google_pay/google_pay.dart';
void main() => runApp(MyApp());
class MyApp extends StatefulWidget {
@override
_MyAppState createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
String _platformVersion = 'Unknown';
String _googlePayToken = 'Unknown';
@override
void initState() {
super.initState();
initPlatformState();
}
// Platform messages are asynchronous, so we initialize in an async method.
Future<void> initPlatformState() async {
String platformVersion;
// Platform messages may fail, so we use a try/catch PlatformException.
try {
platformVersion = await GooglePay.platformVersion;
} on PlatformException {
platformVersion = 'Failed to get platform version.';
}
await GooglePay.initializeGooglePay("pk_test_H5CJvRiPfCrRS44bZJLu46fM00UjQ0vtRN");
// If the widget was removed from the tree while the asynchronous platform
// message was in flight, we want to discard the reply rather than calling
// setState to update our non-existent appearance.
if (!mounted) return;
setState(() {
_platformVersion = platformVersion;
});
}
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(
title: const Text('Plugin example app'),
),
body: Center(
child: Column(
children: <Widget>[
Text('Running on: $_platformVersion\n'),
Text('Google pay token: $_googlePayToken\n'),
FlatButton(
child: Text("Google Pay Button"),
onPressed: onButtonPressed,
)
]
),
),
),
);
}
void onButtonPressed() async{
setState((){_googlePayToken = "Fetching";});
try {
await GooglePay.openGooglePaySetup(
price: "5.0",
onGooglePaySuccess: onSuccess,
onGooglePayFailure: onFailure,
onGooglePayCanceled: onCancelled);
setState((){_googlePayToken = "Done Fetching";});
} on PlatformException catch (ex) {
setState((){_googlePayToken = "Failed Fetching";});
}
}
void onSuccess(String token){
setState((){_googlePayToken = token;});
}
void onFailure(){
setState((){_googlePayToken = "Failure";});
}
void onCancelled(){
setState((){_googlePayToken = "Cancelled";});
}
}
