I used to work with Flutter v2.8 as much as I expected. because of the Firebase, I had to update flutter to v3 to get it to work.
After updating Flutter to v3, flutter said, "You have to get JDK version 11 or newer". I got confused why it was saying that because "flutter.dev" has mentioned the appropriate version of JDK for flutter is 8 so far!
I updated my JDK to 11 then, I got these weird errors that I've never had before! every time that I run or build an app it says something like the following pictures:
I created this project by using this command: flutter create projectName

On Windows, i work with Flutter using Android Studio.
Since i was facing some issues before this one, i have successfully uninstalled and reinstalled the latest versions of both Android Studio and Java.
So, on this machine, i have:
Android Studio Electric Eel 2022.1.1.19
jdk 19 C:\Program Files\Java\jdk-19
jre 1.8 C:\Program Files\Java\jre1.8.0_361
Since Android Studio uses its own jre, i have copy-pasted the content of jdk folder into C:\Program Files\Android\Android Studio\jre
Environment variables are properly set: JAVA_HOME leads to C:\Program Files\Java\jdk-19 and Path contains both C:\Program Files\Java\jdk-19\bin and C:\Program Files\Java\jre1.8.0_361\bin
This is the problem i'm facing now if i try to build my flutter project:
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':device_info_plus:compileDebugJavaWithJavac'.
> Could not find tools.jar. Please check that C:\Program Files\Android\Android Studio\jre contains a valid JDK installation.
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.
* Get more help at https://help.gradle.org
BUILD FAILED in 13s
Exception: Gradle task assembleDebug failed with exit code 1
Now, the main problem is that the file tools.jar DOES NOT EXIST AT ALL.
Is there a way to fix this?

Android Studio builds and launches native Android apps without any issue
Eventually i found the solution: here it is, hoping to help someone in the future.
Note: I had to download the jdk-17 because as of today jdk-19 would not work with flutter.
You need to add the path to find your java jdk into your projectfolder/android/gradle.properties file.
simply add this line
org.gradle.java.home=C\:\\Program Files\\Java\\jdk-17
here's my gradle.properties file to give an example
org.gradle.jvmargs=-Xmx1536M
android.useAndroidX=true
android.enableJetifier=true
android.bundle.enableUncompressedNativeLibs=false
org.gradle.java.home=C\:\\Program Files\\Java\\jdk-17
If you installed jdk into another path, you need to specify that in here

I have Java installed from Adoptium using Brew. I already tried flutter doctor --android-licenses and removed the obsolete version of Android SDK Tools:
What could be wrong?
Follow these steps:
Go to Applications folder and find Android Studio app
Right click on it and hit Show Package Contents
Navigate to Contents, then right click on "jbr"
Hit duplicate
Rename the duplicate folder to "jre"
Done!!
Apparently it's an open issue with Android Studio Electric Eel 2022.1.1 after I upgraded using Brew. The workaround is:
cd /Applications/Android\ Studio.app/Contents
ln -s jbr jre
On Linux Operating System do this
cd /opt/android-studio
then
ln -s jbr jre
For Windows you can try this:
Open a terminal with admin permissions (e.g. Press Win and type "cmd", "powershell" or "terminal", whatever you prefer, and press Ctrl+Shift+Enter)
Then type:
cd C:\Program Files\Android\Android Studio
mklink /D "jre" "jbr"
Hints
If you have installed Android Studio in a different directory change the path.
If there is a almost jre directory you can simply delete it with rmdir /s jre this was the case on my system after an update to Electric Eel (2022.1.1).
I'm trying to build my Flutter app and I keep running into an issue where the build fails and throws the following errors:

How do I resolve this issue ??
Actually google_maps_place_picker uses permission_handler see attached image
try override package to lates version
user
dependency_overrides:
permission_handler: latest version
current latest version for permission_handler ^ 8.3.0
then do flutter clean && flutter pub get
Solution 2 : use other updated package as google_maps_place_picker last update 14 month ago
try one of the following
, run
flutter clean
then restart the emulator
, run
flutter pub get
then restart the emulator
hope its work
I couldn't run the flutter app on android emulator or android phone. I installed the recently released android studio for arm-mac platform on m1 mac. Please answer if I am doing anything wrong here or is it the problem with the release itself.

Go to Applications then right click on Android Studio, then choose "Show Package Contents", create a new folder inside jre named jdk and copy the contents of jre to jdk
This is the link for the fix https://github.com/flutter/flutter/issues/76215#issuecomment-864407892
In 2023.
Go to Applications -> right click on Android Studio -> choose "Show Package Contents".
I have only folder .jbr (not have .jre). So, I create new folder with name .jre and copy folder "Contents" (from .jbr) -> paste to .jre folder.
Open terminal and run: flutter doctor -v
That works for me.
I encountered this issue because I didn't have Java installed. If you can't see a Java icon under System Preferences, Java 7 or later versions is not installed. Link to java.com
I was able to fix my issues by doing the following, I sync my project with Gradle files
I downloaded Java 8 (but I don't think this guy did the work)
2022
First of all, check out did you install Java on your mac.
After that I suggest to install Java 19.
If you finish this step
on command pannel : nano .zshrc
add the below code to the bottom of file;
echo 'export JAVA_HOME="$(/usr/libexec/java_home)"' >> ~/.zprofile
echo 'export PATH="$HOME/.daml/bin:$PATH"' >> ~/.zprofile
That is all.
You are good to go.
I'm using Ubuntu 18.04LTS, Android Studio v3.0.1, installed latest Android SDK API 30 & 29, Android SDK Build tools, Platform tools & Command-line tools(latest),downgraded to java jdk1.8, installed Dart plugin on VSCode, installed Dart and Flutter plugin on Android Studio, installed flutter using snap on terminal.
But when I run flutter doctor, i get this

It says the plugin not installed even after I installed it and restarted android studio as well.
When i run flutter doctor --android-licenses, i get all licenses and accept them by typing Y in the terminal and even after this when i run flutter doctor it still gives me same result.
There was an issue with Java 9 so downgraded JDK to 1.8 and yet issue isn't resolved.
run the following commands
$ export JAVA_HOME=`/usr/libexec/java_home -v 1.8*`
$ flutter doctor --android-licenses
