Wrong TypeScript-types for InputText component

[Christoph-Wagner]

This is a pure typing issue, so the normal bug-template does not make a lot of sense.

File: https://github.com/primefaces/primevue/blob/master/src/components/inputtext/InputText.d.ts

Current

interface InputTextProps {
    modelValue?: string;
}

declare class InputText {
    $props: InputTextProps;
    $emit(eventName: 'update:modelValue', value: string): this;
}

Expected

interface InputTextProps {
    modelValue: string | null;
}

declare class InputText {
    $props: InputTextProps;
    $emit(eventName: 'update:modelValue', value: string | null): this;
}

modelValue?: string is the same as modelValue: string | undefined, per the documentation the default is null, and the .vue file also has props: { modelValue: null },. So undefined can never happen, but null is the default. Typecheckers will correctly complain if I use a potential null value as v-model: vue-tsc output: error TS2322: Type 'string | null' is not assignable to type 'string | undefined'.

This is current in master as of commit 4d1891b

That commit still has modelValue?: string; which does not allow null in the props.
