how to enable persistence storage in firebase in flutter apps? - dart

I am kinda stuck in my project trying to figure out how to enable the persistence data in flutter apps.
How can we do this, I have seen the example on github example here.
But, how can i check if there is any internet connection and if no how can i display the data from the firebase cache stored on the device.
Please, can someone tell me how can i achieve this, any help would be greatly appreciated.
Regards,
Mahi

yes, the persistence is enabled by default as described by #GunterZochbauer for firebase and we dont need to do anything regarding this.
Thanks,
Mahi

How to import MS Outlook events?

I've been told to develop an iOS 7.0 and above app which should include a way to import the user's MS Outlook events and show her such information within the app. This could be a quite general question, but I don't even know if it is possible to do that... Has somebody done something like that? I don't find any starting point, what would be necessary to do to import such events? Would it be mandatory to have an Outlook.com account synchronized in the same device, or could the events be remotely requested?
Any guidance should be appreciated. Thanks in advance
You can use the Exchange Web Services (REST API). See EWS Managed API, EWS, and web services in Exchange for more information.
If you're still looking for it, here is one awesome SDK that can help you with it. Office365 has great set of sample codes and training to help you with it. Hopefully this will come in handy for you. Cheers (:

PFIncrementalStore for iOS...Has anyone made it work?

Has anyone had any success with PFIncremental store? Here: http://sbonami.github.io/PFIncrementalStore/
When I load of the sample project, then add my Parse keys and start the app, I don't see any objects appear in Parse. Additionally, if I implement my own test of the library, and try to save an object, it does not appear in the Parse interface.
Any assistance or insight would be appreciated. Please let me know if there is more information that I can provide.
Thanks in advance.

Any twitter api or complete solutions for monodroid?

Looking for good solution for Twitter login and posting something... but there is no idea for now. How to do it in xamarine( IOS mono has complete solution, but monodroid...) help me please, if somebody knows how to do it.
If you just want to post something then you can easily do this by sending an Intent for use by an external app - e.g. see https://github.com/slodge/MvvmCross/blob/v3/Plugins/Cirrious/Share/Cirrious.MvvmCross.Plugins.Share.Droid/MvxShareTask.cs#L19
If you need a more complete solution then libraries like Tweetsharp have had MonoDroid ports/branches at various times, but I don't know the current status of any of these.
You might also want to take a look at Xamarin.Social. This component will let you tweet from your Xamarin.Android application.
