I updated from 2.1.5 to 2.2.1 and have two bugs now:
Toast ist not working like here: https://github.com/GeekyAnts/NativeBase/issues/836#issuecomment-317072372
and
FAB backgroundColor is not changing. It is always blue.
{Platform.OS != 'ios' &&
<Fab
active={this.state.fabactive}
direction="up"
containerStyle={{ marginLeft: 0, marginBottom: 0 }}
style={{ backgroundColor: '#4CAF50' }}
position="bottomRight"
onPress={() => this.setState({ fabactive: !this.state.fabactive })}>
<Ionicons name="md-more" />
<Button style={{ backgroundColor: '#FFFFFF' }} onPress={this.logout.bind(this)}>
<Ionicons name="md-log-out" />
</Button>
<Button style={{ backgroundColor: '#FFFFFF' }} onPress={() => Linking.openURL('mailto:[email protected]?subject=Feedback%20zur%20Mittagessen-App')}>
<Ionicons name="md-mail" />
</Button>
</Fab>
}
Am i missing something? Same with 2.3.0.
"native-base": "^2.3.0",
"react": "16.0.0-alpha.12",
"react-native": "https://github.com/expo/react-native/archive/sdk-19.0.0.tar.gz",
Got the same issue but I added <Root> tag in my main app and it works, try to check the doc for
https://docs.nativebase.io/Components.html#Toast
Also I didn't post this issue yet but I got again the error evaluating 'this.toastInstance._root' Error when I tried hopping different screen/pages back and fort and the error is showing randomly.

@shuffgy Fab works fine in version 2.3.0
I am experiencing the same issue although I ejected in order to provide some customization. I'll provide an update if I determine the underlying cause.
@eggybot @lanceharper The issue seems to be with android. Will be fixed in the next patch
When will you release the next patch? I'm having the same issue:
evaluating 'this.toastInstance._root' Error
Morover I'm not able to import the Root element:

Any solution?
Next patch will be released by end of this week
@bm-software What version NativeBase are you using
@shivrajkumar Nice! I'm using version 2.3.0
@shivrajkumar Sorry for asking but could you let us know here when the patch has been released?
Thank you very much!
@shivrajkumar Now the problem is solved. Toast works but the import error still exists:

Seems that a typing is missing.
@bm-software Root typing has been added in the latest version v2.3.2
@shivrajkumar Unfortunately the evaluating 'this.toastInstance._root' Error issue is still present but I'm getting it only on Android release builds, on developer build (while testing) it's not present.
I think that this issue should be reopened.
Any news on this? I'm getting the same error on Android.
