Web3Model version 3.2.0 error when building ':package_info_plus:compileReleaseJavaWithJavac'. > error: invalid source release: 17

[Luism96xd]

Describe the bug When I add web3modal_flutter package to my recently created flutter project, I've got this error when I try to run the app on device or building an Android APK.

I tried to change

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

to

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_17
        targetCompatibility JavaVersion.VERSION_17
    }

and the error keeps the same

Steps to reproduce the error:

1. run flutter pub add web3modal_flutter
2. set minSdkVersion to 23 in build.gradle.file
3. flutter build apk

Expected behavior

The flutter app with web3 modal should start and run as the tutorial video. But it does not work, yet

Screenshots

This is the error in my terminal:

Additional context

I followed the following tutorial https://www.youtube.com/watch?v=v_M2buHCpc4 and the Official docs: https://docs.walletconnect.com/web3modal/flutter/installation

I used both versions 3.2.0 (latest) and the same as the video (3.0.20) and nothing worked

I uninstalled all other packages and I haven't written code yet, only installing packages and run

I've got the error in the previous version, too

Hi! Thanks for answering my issue, so I need to add:

dependencies:
  walletconnect_flutter_v2: ^2.2.3

dependency_overrides:
  package_info_plus: ^8.0.0

then I run flutter clean and flutter pub get

but the error persists if I keep web3modal_flutter package

I'm using web3modal_flutter ^3.2.0 package

That means should I use walletconnect_flutter_v2 package? What's the difference between these two? What are things I can do in web3modal and not in walletconnect_flutter_v2

Do you recommend not using web3modal_flutter until issue is fixed?

[quetool]

Hello @Luism96xd If you use Web3ModalFlutter you don't need WalletConnectFlutterV2

WalletConnectFlutterV2 is the core SDK dependency of Web3ModalFlutter

Where do you set minSdkVersion exactly?

[quetool]

Ah wait I see, you have set minSdk in build.grade but the right key is minSdkVersion so it should be minSdkVersion 23

[quetool]

I only installed web3modal_flutter: 3.2.0 then changed defaultConfig to minSdkVersion 23 and it works fine. Without any other override dependency

Thanks for researching, I'm using Flutter 3.22 and when we generate a new project the keys are minSdk and this flutter version and previous one give me this error:

':package_info_plus:compileReleaseJavaWithJavac'. > error: invalid source release: 17

The error persist, with or without dependency override, with minSdk or minSdkVersion, which flutter version are you using?

Thanks in advance
