I've been reviewing the documents and I can't find anything talking about whether or not Litho supports data binding. There is one comment I've found here that says, "It supports one-directional data binding..." but there isn't anything in the docs that outlines how you might use data binding. So does Litho support data binding, if so, how do you use it?
Because Litho uses declarative approach to building UI, binding comes naturally – you just can't change a property on a View in-place, you need to recreate a new Component. So, when a new data comes from whatever source you have, you'll just recreate a Component and set it to LithoView or ComponentTree.
Another way is to pass your Controller as a Prop, subscribe to data changes and on every update of data, call a State Update for the Component, let's say. For subscribing/unsubscribing you can use OnAttached/OnDetached methods: https://fblitho.com/docs/onattached-ondetached
Let me know, if you need more info
