registerWebFDioInterceptorInstaller function
Register a context-aware installer to be invoked for the Dio instance associated with the given context. If the Dio already exists, the installer is applied immediately; otherwise it will be applied on first creation.
Implementation
void registerWebFDioInterceptorInstaller(double contextId, void Function(Dio) installer) {
_WebFDioPool.registerInstaller(contextId, installer);
}
