ArgumentError when calling _tileStore.setMapboxAPIUrl with Uri

**Description:**
I encountered an issue when calling `_tileStore.setMapboxAPIUrl(Uri.parse('https://api.mapbox.com/'));`. This results in the following exception:

```
ArgumentError (Invalid argument: Instance of '_SimpleUri')
```

### Steps to Reproduce:
1. Call `_tileStore.setMapboxAPIUrl(Uri.parse('https://api.mapbox.com'));`
2. Observe the exception being thrown.

### Expected Behavior:
The function should accept the parsed URI and not throw an `ArgumentError`.

### Actual Behavior:
The function throws `ArgumentError (Invalid argument: Instance of '_SimpleUri')`.

### Possible Cause:
It seems like `_tileStore.setMapboxAPIUrl` might be expecting a `String` instead of a `Uri` object, as described in its documentation: "Accepts a string, or null for resetting to the default value." If this is the case, the method should ensure proper type handling.

### Environment:
- **Package Version:** 2.5.1
- **Platform:** Android and iOS

### Additional Context:
Any insights into whether this is an expected behavior or a bug would be appreciated. If `_tileStore.setMapboxAPIUrl` is meant to accept a `Uri`, it might need an update to handle this exception properly.

Thanks!

Start by locating the _tileStore.setMapboxAPIUrl entry point and its documented argument type. Reproduce the failure with Uri.parse and compare it with a string or null input; done means the documented behavior is consistent and the Uri case has a verified outcome on Android and iOS.
