### ProGuard settings

If you use ProGuard or a similar tool that includes shrink or obfuscation rules in your project, you may need to add these exceptions for our SDKs to work properly.

```groovy
-keep class com.iproov.** { *; }
-keep interface com.iproov.** { *; }
-keepclassmembers class com.iproov.** { *; }

-keep class kotlin.** { *; }
-keep class kotlinx.** { *; }

# With R8 full mode generic signatures are stripped for classes that are not
# kept. Suspend functions are wrapped in continuations where the type argument
# is used.
-keep,allowobfuscation,allowshrinking class kotlin.coroutines.Continuation

# R8 full mode strips generic signatures from return types if not kept.
-if interface * { @retrofit2.http.* public *** *(...); }
-keep,allowoptimization,allowshrinking,allowobfuscation class <3>

# With R8 full mode generic signatures are stripped for classes that are not kept.
-keep,allowobfuscation,allowshrinking class retrofit2.Response
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.caf.io/caf-sdk/flutter/standalone-modules/deprecated-sdks.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
