1. Find out your java version by running the command:

   java --version

2. Go to https://docs.gradle.org/current/userguide/compatibility.html#java and find out the gradle version compatible with your java version. mine was 19.0.2 so the matching one is 7.6

3. Go to your project folder and find the file, gradle-wrapper.properties in: android/gradle/wrapper/gradle-wrapper.properties

4. Change the version number of the distribution Url

   for mine: distributionUrl=https://services.gradle.org/distributions/gradle-7.5-all.zip

   to: distributionUrl=https://services.gradle.org/distributions/gradle-7.6- all.zip

5. Rerun the project, gradle should begin downloading a new version. It took a while but it worked for me.

Ps. I tried the approach on the flutter website to upgrade gradle but the command didn't work I guess because the gradle version was incompatible with the Java installed.

This problem because of the new version of Flutter 3.13. I faced this problem and there is a solution:

1. Download the previous version for Flutter, like 3.10
2. Delete your .gradle from your system disk at the path of the folder, like: `C:\Users<your user name>’
3. Rerun the project again

If this doesn't work, do this with the previous steps:

1. Make your system in ENGLISH if the system is in another language
2. Make sure the path of Flutter that you added to the environment variable is in Lowercase and doesn’t have any symbols; here is an example how it should to be: C:\development\flutter\bin

Notice: If the path has any Uppercase or custom symbols, you have to edit the name of the folders in your Windows Explorer, then add the path to environment variable.

3. Make sure your Regional Format in US from: Settings -> Time & Language -> Region -> Regional Format

4. delete your .gradle from your system disk the path of the folder like: C:\Users'your user name

5. Rerun the project again
