instance static method
Additional method that does the same as the factory constructor. Just here for making it more natural to get instances of Vasat
Implementation
static Vasat instance([String name = defaultName]) {
// Return cached vasat for given name. If not found in cache return a new empty Vasat instace
return _cache[name] ?? Vasat(config: VasatConfig(clientId: '', host: ''), storageProvider: VasatSharedPreferencesProvider());
}
