Got the same issue, no more detail.
I'll let you know what my code looks like :

async _loadData(page = 1, callback, options) {
let response = await fetch(url + page);
callback(response.data);
}

and in the render return :
<GiftedListView
rowView={(rowData) => this._renderRow(rowData)}
onFetch={this._loadData}
firstLoader={true} // display a loader for the first fetching
pagination={true} // enable infinite scrolling using touch to load more
refreshable={false} // enable pull-to-refresh for iOS and touch-to-refresh for Android
withSections={false} // enable sections
customStyles={{
paginationView: {
backgroundColor: '#eee',
},
}}

      refreshableTintColor="blue"
    />

ok with this "onFetch={(page, callback, options) => this._loadData(page, callback, options)}" my listview is well rendered. However I still got this error :
TypeError: undefined is not a function (evaluating 'callback(responseJson.data)')

[Aavesh11]

<GiftedListView style={{flex:1}}
automaticallyAdjustContentInsets={false}
rowView={this._renderRow}
onFetch={this._loadDataFromNetwork}
firstLoader={true}
pagination={false}
refreshable={true}
withSections={false}
customStyles={{refreshableView:{backgroundColor: '#FFFFFF'}}}
emptyView={this._renderEmptyView}
ref="listView"

            />

how to use?
