Is your feature request related to a problem? Please describe.
I’ve been using React-Admin since its early days, including the enterprise version for over three years, and have successfully integrated it with React Native for over a year. However, React-Admin’s tight coupling with react-router is a huge limitation — specifically, react-router-native is now deprecated, and I’m locked into an outdated version just to keep things working. This makes long-term maintenance and upgrades difficult.

Describe the solution you'd like
I’d like the router to be moved to a customizable context, similar to how data and auth providers are handled. This would decouple routing from a specific library and make it possible to use React-Admin with any routing solution, including custom ones tailored for native or other platforms.

Describe alternatives you've considered
Currently, I’m using react-router-native as a workaround, but it’s deprecated and not officially supported by either React-Admin or React Router. There’s no long-term path forward with this approach.

Additional context
Allowing routing to be handled via a routing context would greatly expand the flexibility of React-Admin. It would allow projects to integrate seamlessly with alternative routing systems, adapt to React Native and other environments, and reduce the tight coupling with a single router implementation.
