Context

Context is a set of key and value pairs that your app attaches to what the user sends, for the bot to use

The context goes with the next message, button click or triggered dialogue, and is delivered once. With a chat page loaded it reaches the chat at once, and the chat merges it with context it already holds, so two calls before the next message send both maps. Without a loaded page the SDK keeps only the latest map and delivers it to the next page

Keys and values are strings. A map can hold up to 100 entries, with keys of 1 to 256 characters and values of up to 4,096 characters, and a key cannot be __proto__, constructor or prototype. The SDK refuses a map that breaks these rules with an error in the log. Flutter checks the three reserved keys before the call and throws an ArgumentError, and React Native throws a KindlyWebViewError with the code INVALID_ARGUMENT for them and for a value that is not a string

This withdraws the context set with setNewContext, including context the chat page already received

To attach context to a single message instead, pass it with the message, see Send a Message
