Retrieve User Profile Data

Retrieving User Profile Data

Overview

This section focuses on how to retrieve a user's profile data using the SDK. The getProfile method is designed to access the demographic data of a user.

Method Signature

The getProfile method is defined as follows:

suspend fun getProfile() : BWellResult<Person>

• BWellResult<Person>: The method returns an object representing the user's demographic data.

Sample Code

Here's how you can use the getProfile method within a coroutine to fetch user profile data:

suspend fun fetchUserProfile(): Flow<BWellResult<Person>?> = flow {
    val profileData = BWellSdk.user?.getProfile()
    if (profileData?.operationOutcome?.status == Status.SUCCESS) {
        emit(profileData)
    }
}

Detailed Explanation

1. Profile Data Retrieval:

   • BWellSdk.user?.getProfile(): This call attempts to retrieve the user's profile data. The use of the safe call operator (?.) ensures that the method is called only if the user object is not null.

2. Handling the Result:

   • The method checks if the operationOutcome status of the retrieved profile data is SUCCESS.
   • If successful, the profile data is emitted to the calling function.

3. Flow Usage:

   • The method fetchUserProfile returns a Flow<BWellResult<Person>?>. Using Flow allows for asynchronous data streams, which are particularly useful in reactive or real-time applications.

Best Practices

• Null Safety: Always check for nullability (?.) when dealing with user data to prevent unexpected crashes.
• Success Status Check: Verify the operationOutcome status to ensure that the data retrieval was successful before using the data.
• Asynchronous Handling: Use Kotlin coroutines and Flow for efficient, non-blocking data retrieval, especially when dealing with potentially long-running operations like network requests.
• Error Handling: Implement additional error handling within the flow to manage scenarios where the profile retrieval fails or the user data is not available.
