Modelprovider class error

zamargab commented 2 years ago

Description

I have been using Amplify plugins of versions 0.2.2, I just upgraded to versions 0.4.1 and I am facing an issue, My Modelprovider class that was auto generated by Amplify shows an error and when I try to inspect the error, I get the error message below

Missing concrete implementations of 'getter ModelProviderInterface.customTypeSchemas' and 'setter ModelProviderInterface.customTypeSchemas'. Try implementing the missing methods, or make the class abstract.

Steps to Reproduce

Upgrade all Amplify packages from version 0.2.2 to 0.4.1
Run flutter clean
Build app

Hi @zamargab - can you try regenerating your models by running amplify codegen models?

Note: you'll need to have CLI version >=7.6.10. You can run npm install -g @aws-amplify/cli to get the latest.

zamargab commented 2 years ago

Even after update CLI, my problem was not solved. I solved it by adding line below to ModelProvider class

List customTypeSchemas = [];

is this a good fix?

HuiSF commented 2 years ago

The manual fix works but it should not be required. Tips:

Run amplify --version to double check which version was installed
Run amplify uninstall -g @aws-amplify/cli before install the latest version
Make sure you don't have multiple versions of Amplify CLI installed in your system (e.g. global installation vs project installation)
Run npm list -g --depth=1 check the version of amplify-codegen it should be 2.28.0
