Cannot read property 'LENGTH_LONG' of undefined

When I try to include and run I get the following error,

Hi @gokulkulkarni1987, this means that the Snackbar object itself is undefined. Please make sure you've run react-native link react-native-snackbar successfully, then rebuild your app using react-native run-ios or react-native run-android.

@cooperka I am very new to React Native, so I do not know when react-native link react-native-snackbar will be successful.

I ran react-native link react-native-snackbar and also tried this link But still it did not work.

[cooperka]

Could you try running the example app and see if you spot any differences?

Here's my successful output for react-native link:

%> react-native link react-native-snackbar
Scanning 552 folders for symlinks in /home/react-native-snackbar/example/node_modules (2ms)
rnpm-install info Android module react-native-snackbar is already linked 
rnpm-install info iOS module react-native-snackbar is already linked

The example does work, I check my config with the config in this example and keep you posted.

hi @cooperka thanks it worked. I had issue with react-native version, after updating to latest version it did work. Thanks for your support.

Same problem using react-native 0.48.3 version and react-native-snackbar 0.4.1 version. Not sure how to resolve it as of yet...

[cooperka]

Hi @mattferrin, this error generally means the library wasn't linked properly or React Native can't find it. Can you please clear all your caches and try once more? Often something small gets in the way and the only solution is starting over.

Hi @cooperka I have upgraded my react-native version to 0.49.3 and I have started the getting the issue yet again. :(

Please find below the output of link,

sudo react-native link react-native-snackbar
rnpm-install info Android module react-native-snackbar is already linked 
rnpm-install info iOS module react-native-snackbar is already linked 

react-native: 0.49.3
react-native-snackbar: 0.4.2

please help me out.

Hmm, I upgraded the example app to RN v0.49 and it all still seems to be working for me.

It's likely still a cache issue; try cleaning everything, including Xcode derived data, watchman, and the React Packager. I run into these sorts of issues occasionally, most often because Xcode is storing all sorts of derived data in various places. You can search online for ways of cleaning it up (unfortunately it's not as simple as just running Clean or deleting your project).

Tried everything, didn't work. But it works in fresh new project. Another one of those instances where the only fix is to create new project and then copy over, install, and link everything from scratch... Not the first time; not the last time.

i'm having this issue when i'm running the tests. i've done everything but nothing seems to work.
i'm on the last version of react-native (v0.50)

pls help

[mattferrin]

By the way, I created a new project and copied everything over, installed, and linked everything from scratch. It didn't work :) haha.
