    Class UntypedDynamicComponentRule

    Detects .instance accesses on ComponentRef-typed expressions that lack an explicit type contract. Dynamic component hosts that access component members through an untyped (or any-typed) ComponentRef create implicit contracts that the TypeScript compiler cannot verify.

    Detection scope:

    • PropertyAccessExpression nodes whose name is instance and whose expression resolves to a type that includes ComponentRef.
    • Only flagged when the .instance access is itself chained with a member access (.instance.memberName), indicating an actual contract use.

    Skipped:

    • .d.ts declaration files.
    • ComponentRef<T> where T is a concrete (non-any, non-unknown) named type: the contract is already explicit.
    • Accesses preceded by a type assertion (as IMyInterface or <IMyInterface>), which means the developer has opted in to explicit typing at the call site.
    • Event member accesses when checkEventSubscriptions config option is false.
    const rule = new UntypedDynamicComponentRule();
    const results = await rule.analyze(createContext(sourceFile, project));
    // results[0].metadata.accessedMember   -> 'setData'
    // results[0].metadata.memberType       -> 'method'
    // results[0].metadata.isFullyUntyped   -> true
