Method Usage

Await is Must

It is crucial to use await with all methods due to API calls and for better state management.

Return Method Usage

To utilize return methods, assign your method call to a Request or var type variable.

See simple example:

 var response = await whatsapp.sendMessage(
     phoneNumber: '+91XXXXXXXXXX',
     text: "Welcome to WhatsApp Flutter."
 );

response.isSuccess(); //return method

See better example:

var res = await whatsapp.sendMessage(
  phoneNumber : 'PHONE_NUMBER',
  text : 'text_message',
  previewUrl : true,
);

if (res.isSuccess()) {
    // when message sent
    //Return id of message
    debugPrint('Message ID: ${res.getMessageId()}');

    //Return number where message sent
    debugPrint('Message sent to: ${res.getPhoneNumber()}');

    //Return exact API Response Body
    debugPrint('API Response: ${res.getResponse().toString()}');
} else {
    //when something went wrong
    //Will return HTTP CODE
    debugPrint('HTTP Code: ${res.getHttpCode()}');

    // Will return exact error from WhatsApp Cloud API
    debugPrint('API Error: ${res.getErrorMessage()}');

    // Will return HTTP Request error
    debugPrint('Request Error: ${res.getError()}');

    //Return exact API Response Body
    debugPrint('API Response: ${res.getResponse().toString()}');
}

It is important to understand how to use the methods provided by the whatsapp library. Make sure to review the return methods documentation at docs/return-methods

Phone Number Format

The Phone number you can add followed by the country code with + sign or without. For example: +91XXXXXXXXXX or 91XXXXXXXXXX.
