Flutter: Java uses or overrides a deprecated API - mealwormsws - 07-21-2023
I've been trying to use the auth, firestore firebase in an Android / IOS flutter application, and have been experiencing many different issues, after testing several different versions. Now it's showing me several messages in the build log.

You need to use the following plugin:
```
dependencies:
firebase_auth: ^0.15.3
cloud_firestore: ^0.13.0+1
```
Don't forget to configure firebase:

Also in your `app/build.gradle`, increase the `minSdkVersion`:
Change this:
```
minSdkVersion 16
```
into this:
```
minSdkVersion 23
```
RE: Flutter: Java uses or overrides a deprecated API - kith784393 - 07-21-2023
In order to use **minSdkVersion** below 21 you will have to configure your app for multidex like this:
android {
defaultConfig {
...
minSdkVersion 15
targetSdkVersion 28
multiDexEnabled true
}
...
}
dependencies {
implementation "androidx.multidex:multidex:2.0.1"
}
After this please run the
flutter pub upgrade
flutter pub get
flutter clean
flutter run
It will still throw the warning after **flutter clean**, but at least it will be possible for supporting earlier versions.
More to check out on [official docs][1]

RE: Flutter: Java uses or overrides a deprecated API - bebeeeh - 07-21-2023
In my case, Open terminal and Run:
1. Run: flutter clean => Clean cache.
2. Run: flutter pub outdated => Findout what libraries need to upgrade.
3. Run: flutter pub upgrade => Upgrade libraries.
4. Run: flutter pub get.
5. Run: flutter run.
Good luck!

I also got errors with my project when using Firebase services(core, auth, cloud firestore), but I decided to get into this problem only when building an appbundle:
[![screen with error in the console][1]][1]
fixed it with part of the chosen answer, by increasing **minSdkVersion** in *android/app/build.gradle*
from:
defaultConfig {
...
minSdkVersion 21
...
}
to:
defaultConfig {
...
minSdkVersion 23
...
}
Аnd then the error that I get of project building disappears:
