When i run my flutter app from vs code it shows this error, what is wrong here?

回答1:

Here are the steps that I followed to solve the problem.

1. run flutter run on the command prompt given by your OS(not by the vs code shell).

2. make sure you have a good internet connection.

回答2:

For me, the problem was that my internet connection could not download the Gradle binaries while initializing Gradle. I suspect it's because I'm behind a proxy.

Try downloading it and installing it manually.

1. Download the latest Gradle version.
2. Extract the ZIP file to a location on your PC, i.e C:\Gradle
3. add the environment variable GRADLE_HOME to point to this location.
4. add GRADLE_HOME/bin to your PATH environment variable.

This might help if you have license problem.

1. run flutter doctor on command prompt. If you get this: ! Some Android licenses not accepted.
2. run flutter doctor --android-licenses and accept all the licenses.
3. now run flutter run and you are good to go.

回答4:

The problem is with your gradle installation, for linux users:

1. Navigate to .gradle folder in your Home directory
2. Open wrapper/dists and you'd find all your gradle installation
3. If you find just one delete it and re-run your dart code from vs-code
4. Ensure you have a good internet as the process would try to download a new gradle.
5. In case you have more than one gradle installed go back to vs-code and take note of what version of gradle it is complaining about.
6. Delete that version and re-run your dart code (don't forget to get a good internet).

回答5:

Delete .gradle the folder in C:\Users***.gradle in Windows or /Users/xxxx/.gradle in Mac , connect to the internet, rebuild project to download the latest Gradle.

回答6:

Open gradlew.bat file in edit mode in the new window of android studio and resolve the gradle issue. I Just delete gradle-4.10.2-all and rebuild my project.

回答7:

I solve this error with delete flutter sdk and download it again. Be sure that you have good internet.

    defaultConfig {
    // TODO: Specify your own unique Application ID 
        (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.match_hire"
        minSdkVersion 16
        targetSdkVersion 28
        multiDexEnabled true
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
   }

add multiDexEnabled true might work

I have solved this issue by setup android project in android studio and android studio shows me error that your kotlin version is not compatible so i upgrade kotlin version.

ext.kotlin_version:   '1.2.71' ->  '1.3.50'

It started working fine.
