Retrieving file data synchronously from memCache

## 🚀 Feature Requests

Currently, the getFileFromMemory function retrieves file data asynchronously using async/await. However, in certain scenarios, it would be beneficial to retrieve the data synchronously without waiting for the async operation to complete.
### Contextualize the feature

### Describe the feature

### Platforms affected (mark all that apply)
- [ ] :iphone: iOS
- [ ] :robot: Android

Start by locating getFileFromMemory and tracing how it currently retrieves cached file data. Clarify which platforms and synchronous behavior are required, then define tests that demonstrate retrieval without awaiting; the issue does not name any files or existing tests.
