[React 19] Get context value in class component constructor

I updated version of react from 18.2.0 to 19.1.0 (@types/react to 19.1.6, @types/react-dom to 19.1.5).

After the update I received several components with such errors:

Argument of type 'typeof SplitCostDialog' is not assignable to parameter of type 'ComponentType<never>'.
  Type 'typeof SplitCostDialog' is not assignable to type 'ComponentClass<never, any>'.
    Target signature provides too few arguments. Expected 2 or more, but got 1.

I found the reason. I use context in class constructor.

export class SplitCostDialog extends React.PureComponent<ISplitCostDialogProps, IState> {
    static contextType = ResourcePlanContext;
    declare context: IResourcePlanContext;

    constructor(props: ISplitCostDialogProps, context: IResourcePlanContext) {
        super(props);

        const { scope, position } = context.modals.splitPositionCost;
        this.state = { form: new SplitCostForm(scope, position) };
    }

    ...

}

How can I use context inside a constructor after updating to version 19?
I didn't find the answer in the guide.

Inizia con la guida all’aggiornamento di React 19 collegata nell’issue e confrontala con l’esempio segnalato del costruttore di un componente di classe. Documenta come debba essere gestito l’accesso al contesto nei costruttori dopo l’aggiornamento, includendo le indicazioni di migrazione pertinenti, in modo che la guida risponda chiaramente a questo caso.
