Project won't compile because of Android X - flutter

I've cloned a project on Github. It uses different plugins.
dependencies:
flutter:
sdk: flutter
cupertino_icons: 0.1.2
firebase_auth: 0.7.0
google_sign_in: 3.2.4
cloud_firestore: 0.8.2+3
image_picker: 0.4.12+1
shared_preferences: 0.4.3
firebase_storage: 1.0.4
cached_network_image: 0.7.0
intl: 0.15.7
There is blog post which advises keeping versions the same. My problem is the image_picker plugin. Looking around stackoverflow it recommends using version 0.4.12+1 if you don't want to migrate app to Android X. Here is my error

The Gradle failure may have been because of AndroidX incompatibilities in this Flutter app.

I'm wondering what might be causing the incompatibilities prevent my app from compiling?

You need to flow the documentation for AndroidX compatibility

The best option is migrate the app for androidX. Follow the steps in android-studio:
1) Remove all your dependencies of your pubspec file and run flutter packages get
2) Open only android module of your app in android-studio. You can do this with right click on your project root directory > flutter > Open android module in android studio
3) After open only android module in android-studio menu go to Refactor > MigrateToAndoridX...
4) Do the migration!
5) Close android module android-studio instance and go back to your flutter project
6) Insert all your dependencies in pubspec file and run flutter packages get

Use image_picker: ^0.6.6+1 and add AndroidManifest.xml following:
<uses-permission android:name="android.permission.INTERNET"/>
This way worked for me!

How to resolve "Exception: Gradle task assembleDebug failed with exit code 1"?

Flutter Version: 2.6.0-12.0.pre.381
Dart Version: 2.15.0
Gradle version : distributionUrl=https://services.gradle.org/distributions/gradle-6.7-all.zip
In pubspec.yaml, I have these packages:

Same packages are working in another project.
Any suggestions on how to fix the problem. I think it is due to some error in build.graddle.
I have changed minSdkVersion and targetSdkVersion in build.gradle as follows:
minSdkVersion 23
targetSdkVersion 29
multiDexEnabled true
It is showing error while running the project:

Exception: Gradle task assembleDebug failed with exit code 1
This is happing due to compileSdkVersion. Head over to android/app/build.gradle and change complieSdkVersion to 31.
android {
compileSdkVersion 31
...
}
In pubspec.yaml file :-
dependencies:
permission_handler: ^8.2.5
The error must be happening in versions 8.2.0 and onwards. If you still encounter some error then install a version less 8.2.0.
Faced the same issue and this is how i solved it:
First i removed permission_handler from my yaml file.
Then did a flutter clean.
In pubspec.yaml : I changed the version of the permission_handler plugin from 8.2.6 to:
permission_handler: ^8.2.0
Then In android/app/build.grale file:changed compile sdk version to 31.
I think that Build.VERSION_CODES.R is API Level 30 , so setting compileSdkVersion to 30 should fix the issue .
I changed permission_handler: ^8.1.4+2 with permission_handler: 6.0.0 in pubspec.yaml .Now project is working fine. Thanks for your assistance.

Why can't java find twilio?

I am using Eclipse with Gradle. Twilio is listed as dependency. All versions are up to date. Code referencing Gradle will not compile and returns error messages that the Twilio classes do not exist. Code online is frustratingly outdated. I'm hoping someone here can help.
The Code I am running is very basic:

public class SmsSender {
public static final String ACCOUNT_SID = "**Redacted**";
public static final String AUTH_TOKEN = "**Redacted**";
public static void main(String[] args) {
Twilio.init(ACCOUNT_SID, AUTH_TOKEN);
Message message = Message.creator(
new PhoneNumber("**redacted**"),
new PhoneNumber("**redacted**"),
"Message testing.")
.create();
System.out.println(message.getSid());
//sendMessage("**redacted**");
}
public void sendMessage(String numToSend) {
String n = numToSend;
Message message = Message.creator(
new PhoneNumber(n),
new PhoneNumber("+**(redacted)**"),
"Message testing.")
.create();
System.out.println(message.getSid());
}
}

I don't see any problem with your project setup. You can compare it to this reference project.
So, I suspect the problem you're seeing is related to how Eclipse imports Gradle projects. I'm not a regular Eclipse user but I did try it out for this question. When I imported the project in the above repo I saw import errors similar to yours. I was able to fix them by first telling Eclipse that this is a Gradle project (Project context menu > Configure > Add Gradle Nature) then refreshing the project (Project context menu > Gradle > Refresh Gradle Project). I got those steps from this answer. Then everything was working.

It looks like you made a misspell somewhere in the source files. Try to lookup your project directories for files with "contrllers" instead of "controllers".
