Issues from test run #50

Open mraible opened 3 years ago

mraible commented 3 years ago

I installed this module tonight and tried to create an app and run it. First of all, am I supposed to run yo jhipster-flutter-merlin in a directory next to my JHipster app, or inside my JHipster app?

I'm using Java 8 because I got a NoClassDefFoundError: javax/xml/bind/annotation/XmlSchema when I tried to use Java 11.

$ java -version
openjdk version "1.8.0_242"
OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_242-b08)
OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.242-b08, mixed mode)

I tried to create flutter-app next to my JHipster app. After I created the app, I tried to run it with flutter run on Chrome. The error I received:

$ flutter run

Then, I tried Android. That fails too. I must be doing something wrong.

I'm guessing you don't support OIDC auth yet since there are open issues for Keycloak and Okta. If it helps to create bug bounties for these, I'd be happy to do that.

If I generate a reactive app with JWT for auth, should it work?

merlinofcha0s commented 3 years ago

Hi,

Sorry for the late answer.

Yes, you are supposed to launch yo jhipster-flutter-merlin in your generated jhipster project.

Normally you are supposed to use the java version linked with the Android SDK that you downloaded. I'm not sure that it will work with regular JDK but not 100% sure (see screen capture below).

For your last problem, You have either to use the generated launcher present in the run configuration (.idea) it's because all the libraries are not ready for null safety so you have to add --no-sound-null-safety with your flutter run : flutter run --no-sound-null-safety.

Sure, for the bug bounties, it will be awesome !

And yes it will work with JWT reactive or not.

Tell me if something wasn't clear enough.

I tried this again tonight with my jhipster7-demo app that uses JHipster v7.0.1 and JWT for auth.

When I run flutter run --no-sound-null-safety, I get the following error:

    ** BUILD FAILED **

Xcode's output:

You should run " flutter pub run build_runner build --delete-conflicting-outputs", this will update (or create if not exist) the file main.mapper.g.dart, that's because of dart_json_mapper_flutter lib. It is an issue of build runner that didn't display some errors! (in this case, dart version between your drat sdk and targeted by the generated code)

Also, notice that this jhipster module does not support JHipster 7, but with some workaround it will as I did for one of my projects based on JHipster 7, notice also the null safety issues with generated pubspec, here it mine after updating some libs: ` environment: sdk: ">=2.14.0 <3.0.0"

I tried updating my dependencies. See https://github.com/mraible/jhipster7-demo/pull/7/commits/c9f4babfa7ddb84a4d88260b9b078f7b637ce2a9 for specific versions.

Now if I run:

flutter pub run build_runner build --delete-conflicting-outputs

It seems to succeed:

[INFO] Succeeded after 12.7s with 1 outputs (1 actions)

When I try flutter run, it seems to want to connect to Chrome. Is there something I need to do after running this command to see the app?

After solving the above error by catching null values, I get the following error:

The following StateError was thrown while handling a gesture:
