Your flatlist tutorial help me lot it was awesome.
I am having query regarding flatlist. If you will provide any suggestion I will be much obliged.

Query
I have Flatlist which has n-number of buttons, when a user click on any button then that specific button should change its styling.

When executing sends me the following error, do you know what I'm doing wrong?

I used the code that is published

Invariant Violation: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.

Check the render method of FlatListDemo.

This error is located at:
in FlatListDemo (at withExpoRoot.js:22)
in RootErrorBoundary (at withExpoRoot.js:21)
in ExpoRootComponent (at renderApplication.js:34)
in RCTView (at View.js:44)
in RCTView (at View.js:44)
in AppContainer (at renderApplication.js:33)

• node_modules\react-native\Libraries\Renderer\oss\ReactNativeRenderer-dev.js:9710:8 in reconcileSingleElement
• ... 21 more stack frames from framework internals

I tried to run the the project with the steps mentioned, unfortunately i ends up getting this error

element type is invalid.Expected string or class but found undefined

When I run the application, before doing any user input (scrolling the to bottom), there is many calls made to handleLoadMore() (onEndReached). The list is appending new data without need!

It looks like an infinite loop...

Im having an issue. May be a simple issue. Trying to run the demo by the directions and getting 'No bundle URL present'.

Here's the stack overflow question:
