Typing issue

[juliusspencer]

In the index.d.ts there is the following:

declare const _default: ({getItemHeight, getSeparatorHeight, getSectionHeaderHeight, getSectionFooterHeight, listHeaderHeight}: Parameters) => (data: {
    title: string;
    data: any[];
}[], index: number) => {
    length: number | undefined;
    offset: number;
    index: number;
};

In the react-native SectionList is:

getItemLayout?: (
        data: any,
        index: number
    ) => {
        length: number;
        offset: number;
        index: number;
    };

I'm getting a TS error like so:

 Type '{ length: number | undefined; offset: number; index: number; }' is not assignable to type '{ length: number; offset: number; index: number; }'.
            Types of property 'length' are incompatible.
              Type 'number | undefined' is not assignable to type 'number'.
                Type 'undefined' is not assignable to type 'number'.

Would it be possible to change:

length: number | undefined;

to match react-native

 length: number;

I'm not sure if this is possible, it's just that I get a TS error. Or maybe it's how I'm using it. :)
