Warning : Failed child context type: Invalid child context 'virtualizedCell.cellKey' of type 'number' supplied to 'CellRenderer', expected 'string'
To fix the error in any list components where a keyExtractor is in use, update the Component (FlatList etc) to have a string key with .toString(). All keys must now be string values.
Like below;
keyExtractor={item => item.index_id}to
keyExtractor={item => item.index_id.toString()}This change is a requirement for all uses of a keyExtractor so that would include React-Native components like; FlatList and ActionSheet.
keyExtractor={(item, index) => index.toString()}This will solve the warning given by React and React Native.
You could try this solution:
keyExtractor={(item, index) => item + index.toString()}
