Flutter

I’ve downloaded the Flutter template from my first app, but when I tried to run, I received a lot of warnings and a Error:

Hi @Dario_Castaneda

Hi @Dario_Castaneda

We have uploaded a new Flutter SDK version 1.1.6. Please update the version of backendless_sdk package to 1.1.6 in your pub spec.yaml:

backendless_sdk: ^1.1.6

and let us know if it works for you.

Best Regards,

Hi,

We cannot reproduce this issue. Can you please attach the project so we could check it?

sure, demo.zip (168.1 KB)

It’s the template downloaded, without changes (only backendless_sdk version upgrade)

Thank you. We will check it out and give you a feedback as soon as possible.

Hi @Dario_Castaneda

Sorry for the inconvenience. There was another issue due to Swift SDK update. We’ve fixed it and released new version 1.1.7.
Please update the Flutter SDK version in your pubspec.yaml

backendless_sdk: ^1.1.7

and run the following commands:

cd ios
pod update

Please let us know if it works for you.

Best Regards,

Hi,

I’ve downloaded again the generated demo from my Serverless Project (Download Project template option in the top page of my App), later, modified the serverless_sdk version to ^1.1.7 and update the ios pods, but I receive several errors, attached you will find the log generated

Thank you for following up

demo.log (13.2 KB)

Seems like the pods are cached and not updated properly. Can you please update it again with the following commands:

cd ios
pod deintegrate
pod update

Regards,
Maksym

Thank you,

I found that update pods still using backendless_sdk (0.0.1)

so, what I did was delete the ios folder and recreate ios folder (flutter create -i swift .)

Now works and the demo save the information in TestTable.

I appreciate your help and support

I am glad you resolved the issue. Happy coding with Backendless!
