Flutter点击实现拨打电话

1.创建服务TelAndSmsService .dart

import 'package:url_launcher/url_launcher.dart';
class TelAndSmsService {

  void call(String number) => launch("tel:$number");
  void sendSms(String number) => launch("sms:$number");
  void sendEmail(String email) => launch("mailto:$email");
}

2.注册服务工具类

GetIt locator = GetIt();
void setupLocator() {
  locator.registerSingleton(TelAndSmsService());
}

3.注册服务，注意注册服务放在程序刚开始加载时，要不然会导致多次注册

1 2	// 注册服务 setupLocator();

4.调用打电话

final TelAndSmsService _service = locator<TelAndSmsService>();
final String number = "123456789";
//点击事件
onTap: (){
      _service.call(number);
    },
