Function ProvideContext

ProvideContext<K extends keyof ContextMap>(key: K): PropertyDecorator
Alpha
Decorator that exposes a property's value to descendants as the named ContextMap key.

Descendants reading the same key via SelectContext resolve the closest enclosing provider. Reassigning the property propagates the new value to subscribers automatically.
Type Parameters
- K extends keyof ContextMap
  The ContextMap key being provided.
Parameters
- key: K
  The ContextMap key to provide.
Returns PropertyDecorator
A PropertyDecorator that wires up the provider.
Example
```
@Prop()
@ProvideContext('user')
public user: User;
```
Example
```
@State()
@ProvideContext('user')
private user: User;
```
