Usage #

import 'package:easysms/easysms.dart';

final easysms = EasySMS(
  gateways: [...] // Gateway list
);

final message = Message.fromValues(
  template: '<You template ID>',
  data: {
    'SignName': "<You sign name>",
    'TemplateParamSet': [
      '<Param 1>',
      '<Param 2>',
      // ...
    ],
  },
);

main() async {
  final phone = PhoneNumber('<You country code>', '<You phone number>');
  final response = await easysms.send([phone], message);

  print('Status: ${response.first.success}'); // true or false
}

Message #

You can create your own scene messages based on the message:

import 'package:easysms/easysms.dart';

class OneTimePasswordMessage implements Message {
  final String password;
  final Duration ttl;

  OneTimePasswordMessage(this.password, this.ttl);

  @override
  Future<Map<String, dynamic>> toData(Gateway gateway) {
    // ...
  }

  @override
  Future<String> toTemplate(Gateway gateway) {
    // ...
  }

  @override
  Future<String> toText(Gateway gateway) {
    // ...
  }
}

Built-in Message #

formValues

final message = Message.fromValues(
  text: '<You message text>',
  template: '<You template ID>',
  data: {
    // ...
  },
);

fromCallbacks

final message = Message.fromCallbacks(
  text: (gateway) async => '<You message text>',
  template: (gateway) async => '<You template ID>',
  data: (gateway) async => {
    // ...
  },
);

Gateways #

If the platform you need to use is not listed here, you have several ways to support it:

1. Create an issue to request support for the platform.
2. Create an pull request to add support for the platform.
3. You can create a gateway Dart package yourself,
4. You can implement the gateway yourself in your project without telling anyone.

How to create a gateway #

You must depend on the easysms package and implement the Gateway interface:

import 'package:easysms/easysms.dart';

class MyGateway implements Gateway {
  @override
  Future<Iterable<Response>> send(
      Iterable<PhoneNumber> to, Message message, http.Client client) async {
        // ...
      }
}

You can refer to all the gateways we have implemented.

Strategies #

EasySMS allows you to customize the gateway selection strategy.

class MyStrategy implements Strategy {
  @override
  Future<Gateway> select(Iterable<Gateway> gateways) async {
    // ...
  }
}

We implemented a built-in strategy, for example, you can use the OrderStrategy:

final easysms = EasySMS(
  gateways: [...],
  strategy: const OrderStrategy(),
);

Note: The OrderStrategy will select the gateway in the order of the gateway list.
