Why?
Previously, Flipper did not support seamless integration with Flipper Cloud for JavaScript users, forcing teams to rely on local adapters without the benefits of centralized management or cross-platform feature flag sync. Additionally,
MemoryAdapter.disablecleared an entire feature instead of only the relevant gate value, resulting in unintended data loss when disabling boolean or number gates.How?
