### Data/model/auth/Login.kt

```kotlin
package com.matar.app.data.model.auth

import com.google.gson.annotations.SerializedName

data class SendOtpRequest(
    @SerializedName("action") val action: String,
    @SerializedName("name") val name: String = "",
    @SerializedName("phone_number") val phoneNumber: String
)

data class SendOtpResponse(
    @SerializedName("message") val message: String
)
```

**Describing Code:**

The code defines two data classes in Kotlin, **SendOtpRequest** and **SendOtpResponse**, which are typically used for representing data in your application.

1. **SendOtpRequest**:
   * This data class is used to represent a request to send an OTP (One-Time Password).
   * It has three properties:
     * **action**

       (String): This is the action to be performed, which appears to be related to sending an OTP.
     * **name**

       (String, optional): This is the name associated with the request. It's an optional parameter and has a default value of an empty string.
     * **phoneNumber**

       (String): This is the phone number to which the OTP will be sent.
2. **SendOtpResponse**:
   * This data class is used to represent the response received after sending an OTP.
   * It has one property:
     * **message**

       (String): This property holds a message from the server, which might contain information about the status of the OTP sending process.

These data classes seem to be designed for handling authentication-related operations, where you can create a **SendOtpRequest** object to send a request to send an OTP, and you can receive a **SendOtpResponse** object as a response, containing a message.

Please note that these data classes are annotated with **@SerializedName**, which suggests that they are meant to be serialized/deserialized using Gson, a library for working with JSON data in Android and Java applications.

### Data/model/auth/LogoutResponse.kt

```kotlin
package com.matar.app.data.model.auth

import com.google.gson.annotations.SerializedName

data class LogoutResponse(
    @SerializedName("message") val message: String?
)

//data class LogoutResponse(
//    @SerializedName("description") val description: String,
//    @SerializedName("error") val error: String,
//)
```

**Describing Code:**

The **LogoutResponse** class has a single property:

1. \*\*message: \*\*This property is annotated with \*\*@SerializedName("message")\*\*indicating that it's intended to be serialized/deserialized using Gson, a popular JSON parsing library for Java and Kotlin. The property is of type \*\*String? \*\*which means it can hold a nullable string.

This class is likely used to represent the response from a server or API when a user logs out, with the server providing a message to indicate the result of the logout operation
