Tremendous tutorial my man! Thank you

[@cincopura1170]

Hey Kilo, Thank you for a wonderful tutorial. I used it to configure Amplify in my flutter app. however even after setting up every thing I am unable to see my data on AWS Amplify. can you suggest what I would have been missing

[@suryap4527]

Is this only storing data locally? Or is it sychronized with the backend in the console

[@mmathems395]

Good info well explained. Thank you Kilo 😊... I'm here seeking a tutorial that goes into how the local data can be synced to the cloud or AWS database of choice ... Would you be aware of tutorial covering this please?

[@SuperMicroplus]

Hi! Thanks for the tutorial, it's really great to help get started with amplify and flutter! I have a question.. is there a way to perform transactions on the database? if so would you point me in the right direction please!? Thanks again for the great tutorials!

HI I WAS WORKING ON A APP WHERE I NEED TO KEEP TRACK OF WHAT THE USERS IN APP PURCHASE. WHICH IS BEST AWS OR FIREBASE. IF ANY OTHER ALTERNATIVE AVAILABLE PLEASE TELL ME..

Do I need to use Amplify API to push the changes to DynamoDB? I have been using Amplify DataStore and it is persisting only locally. Thanks!

[@navaneetbammanni]

@soumickdasgupta6111 Do u see the table updated visually in the Amplify UI content page after performing create or update function?

[@aniketkumarsinha2537]

where i can see this table in AWS console...in dynamodb?...it did create the database...but the table is empty...

[@abhaychandavar1766]

how to paginate the data being queried? I read through the docs and found this: List posts = await Amplify.DataStore.query(Post.classType, pagination: new QueryPagination(page:0, limit:100)); but I'm not able to invoke QueryPagination, please help me out

[@jrheisler]

Been using Firebase, not bad, but some of my data model doesn't really work well with nosql. I can't really tell, what does amplify expose? I'm not that familiar with graphQL either. I have decades with sql, oracle and sql server. Is there a per read/write charge? Thanks!

[@comfortablesleep202]

How can i handle race condition in 'update()' ??

[@gohoapp]

can this work on a flutter desktop app

[@n.d8123]

Hi is this free to use with an amazon account?

[@n.d8123]

also, how to add to datastore from a form kind of thing? Seems like this example is only for 1 object and is hard-coded? Sorry new to flutter, amplify and datastore. Trying to create some kind of scheduler app.

You can find the Free Tier of Amplify here aws.amazon.com/free/?all-free-tier.sort-by=item.additionalFields.SortRank&all-free-tier.sort-order=asc&all-free-tier.q=amplify&all-free-tier.q_operator=AND If you want to save multiple values, you can create a model with all the different fields that you need saved or you can create multiple models and save each instance.
