Seeing the same warnings.. any solution for this yet ?

[ialexies]

me too :(

[zaheddec]

I see the warning too.

[touhidsunny]

in your android/app/build.gradle file set the minSdkVersion 21
or
add this implementation "androidx.multidex:multidex:2.0.0" in your dependencies at android/app/build.gradle file

[nolliebk]

me too :(

[yuyuman]

in your android/app/build.gradle file set the minSdkVersion 21
and modify compileSdkVersion 29 and targetSdkVersion 29

if it does not work

add this implementation "androidx.multidex:multidex:2.0.0" in your dependencies at android/app/build.gradle file

and modify compileSdkVersion 29 and targetSdkVersion 29

[ThomasValois]

add this implementation "androidx.multidex:multidex:2.0.0" i

and modify compileSdkVersion 29 and targetSdkVersion 29

I've done the above but still getting the errors, also ran flutter clean and all that jazz

flutter build apk
You are building a fat APK that includes binaries for android-arm, android-arm64.
If you are deploying the app to the Play Store, it's recommended to use app bundles or split the APK to reduce the APK size.
    To generate an app bundle, run:
        flutter build appbundle --target-platform android-arm,android-arm64
        Learn more on: https://developer.android.com/guide/app-bundle
    To split the APKs per ABI, run:
        flutter build apk --target-platform android-arm,android-arm64 --split-per-abi
        Learn more on:  https://developer.android.com/studio/build/configure-apk-splits#configure-abi-split

[carlleeswanson]

Am having the same problem.

[FlashJonas]

I had the same issue and combined two suggested fixes to get it to finally work:
1) minSdkVersion 21, change to 23
2) run "flutter pub upgrade"
= issues fixed!

To double-check what the fix was:
I also reverted back to 21, and invalidated + flutter clean and the issue appeared again. Then i changed to 23 and the warnings disappeared!

[ThomasValois]

I did your suggestion but also recreated my emulators and it worked! Now time to fix the many other issues 🙄 Cheers @FlashJonas

[insinfo]

@FlashJonas
But this is not a solution to the problem, because if you change minSdkVersion to 23 the App loses compatibility with Android 5 which is a version supported by Flutter.

[ThomasValois]

This definitely isn't the prettiest of solutions but luckily I am developing this app for in-house use so I'll be using the latest version of Android. However like @insinfo said, this does start limiting the total number of targetable devices!

[gordonturibamwe]

in your android/app/build.gradle file set the minSdkVersion 21
or
add this implementation "androidx.multidex:multidex:2.0.0" in your dependencies at android/app/build.gradle file

This worked for me. Thank you

[carlleeswanson]

(1) For me,

add this implementation "androidx.multidex:multidex:2.0.0" in your dependencies at android/app/build.gradle file

didn't work.

(2) Also, setting

minSdkVersion 21

would build, but continued to give the same warnings as per the OP

(3) The only thing that got rid of the errors/warnings was to set

minSdkVersion 23

Running flutter pub get was also required.

[workerbee22]

None of these changes removed the warning for me. Everyone make sure you do a flutter clean before you declare it resolved for you.

[theRoughCode]

Setting minSdkVersion 21 and running flutter pub get worked for me.
Warning shows only after flutter clean, but on subsequent runs, the warning disappears.

[manisheasyleases]

minSDK Version update worked...thanks for the solution...waster 3 hours on this :(

Hey man. I too had the same issues and running pub upgrade solved it. thank, man

[Salakar]

Hey all, as part of our on-going work for #2582, this has been resolved in our Firebase Firestore rework (#2913) - which has now been merged into master. We'll look at publishing some prereleases in the next few days. Thank you
