      // The height of the row with rowData at the given sectionIndex and rowIndex
      getItemHeight: (rowData, sectionIndex, rowIndex) =>
        sectionIndex === 0 ? 100 : 50,

      // These four properties are optional
      getSeparatorHeight: () => 1 / PixelRatio.get(), // The height of your separators
