Exception thrown in build by image_picker

Question

I am wrestling problems with image_picker for two days now. It started yesterday noon when I tried to debug my application. It would debug fine before and as far as I remember I didn't change anything in that time. It throwed unexpected element <queries> found in <manifest>. error and just like the error log from today below it started Jetfier to solve the incompatibility. The error Jetfier throwed yesterday was something like SDK location not found. Define location in local.properties or with an ANDROID_SDK_ROOT environment variable. But SDK location was defined in local.properties and I also created the ANDROID_SDK_ROOT env. variable with the SDK location but the error stayed the same.

Today I cleared the flutter folder completely and I reinstalled it. After that I had some problems with device-info but eventually it was resolved. Now I am stuck here and I am making no progress whatsoever. If I remove <queries> in AndroidManifest.xml, it is put there again when try to run the program so that's not a solution.

I call it in pubspec.yaml as file_picker: ^2.0.10 under dependencies and I tried pub get, pub cache repair, pub clean in different orders. If I remove the file_picker and all it's uses in the project, rest of the application runs just fine. I tried file_picker in another project, something a lot more basic and it also threw the same exception there.

Below is the error code. If you need anymore details let me know.

The built failed likely due to AndroidX incompatibilities in a plugin. The tool is about to try using Jetfier to solve the incompatibility.

Exception: The plugin file_picker could not be built due to the issue above.

Answer 1

For those who didn't know (including myself) there are two build.gradle files

1. android/build.gradle
2. android/app/build.gradle

step 1 inside android/build.gradle

buildscript {
    ext.kotlin_version = '1.3.50'
    repositories {
        google()
        jcenter()
    }

    dependencies {
        // classpath 'com.android.tools.build:gradle:3.5.0' before
        classpath 'com.android.tools.build:gradle:4.0.1' // after
    }
}

step 2 inside android/gradle/wrapper/gradle-wrapper.properties

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists

# BEFORE
# distributionUrl=https\://services.gradle.org/distributions/gradle-5.6.2-all.zip
# AFTER
distributionUrl=https://services.gradle.org/distributions/gradle-6.1.1-all.zip

step 3 rebuild project

it might take while because it will download new gradle
