I am working on an old project. It worked fine before 5 days ago. Now I am facing an error with agora. I didn't any change on my previous code. here is error-

FAILURE: Build failed with an exception.

Running Gradle task 'assembleDebug'...                             40.0s
Exception: Gradle task assembleDebug failed with exit code 1

I am using agora_rtc_engine: ^3.3.1 bacause this project developed without null-safety (maybe flutter 1.5). How can I solve this problem ?

Answer 1

1.Run flutter upgrade in the terminal to upgrade Flutter

2.Run dart migrate to run the dart migration tool

3.Solve all errors which the migration tool shows

4.Run flutter pub outdated --mode=null-safety to print all outdated packages

5.Run flutter pub upgrade --null-safety to upgrade all packages automatically

6.Check the code for errors and solve them

7.Run dart migrate again and it should now be successful. Follow the link to checkout the proposed changes

8.Press the "Apply Migration" button

9.Check the code for errors again and fix them.

Run flutter run in the command line and the application should run...

Note: If there are any library in you project that don't support null safety you must need to upgrade that library. if that library don’t have null safety remove the library and use another library

Answer 2

So you have to migrate your project to null-safety first and then get

agora_rtc_engine: ^4.2.2

Then you to to your build.gradle and add that last line

  allprojects {
       repositories {
         google()
         jcenter()
    // add this line.
         maven { url ‘https://www.jitpack.io' }
        }
    }

Because following this issue here on GitHub there is no solution for it because this issue has been closed on the agora project.

Answer 3

For anyone who is still facing this issue

1: Run flutter pub outdated --mode=null-safety to check which dependencies are outdated

2: Run flutter pub upgrade --null-safety to upgrade all dependencies

3: It would update agora_rtc_engine to latest sdk, try to change that to agora_rtc_engine: 4.2.2

4: Set ext.kotlin_version = '1.6.10' in *build.gradle

Note: If you face any incompatibility with other packages for setting minSdk as 19, change minSdk to 19

5: If you faced any gradle error, you might need to change gradle-wrapper.properties

//add this line distributionUrl=https://services.gradle.org/distributions/gradle-7.3.1-all.zip

Thats all
