Try any one of the following steps:

  1. Goto Files > Click Invalidate Caches/Restart

  2. Restart your machine

  3. On terminal write flutter clean and then flutter run

I had the same issue after setting up my flutter project to run on iOS. When I tried to run it back on Android, this error was thrown.

This worked for me (on Windows):

  1. Close your project and close your code editor

  2. Open Task Manager

  3. Finish all vscode-related tasks you see (or related to the IDE you are using)

  4. Finish all Java-related tasks, inclidung OpenJDK Platform binary (there are usually two of these; finish both)

  5. Go to your project's root folder and delete the build folder

  6. Open your project again and run

Good luck!

In my case it was enough to exclude only path 'META-INF/DEPENDENCIES' on android/app/build.gradle

android {
  ......
  defaultConfig
  {
   ......
   multiDexEnabled true
  }
  packagingOptions 
  {
    exclude 'META-INF/DEPENDENCIES'
    exclude("META-INF/*") 
  }
 dependencies {
  .......
  implementation 'com.android.support:multidex:2.0.1' 
 }          
}
AndroidManifest.xml
<application
    .......
    android:name="androidx.multidex.MultiDexApplication" >

Now

  • run flutter clean
  • run flutter get

It's worked for me.

The problem is one of the plugins.Usually related to contacts. Flutter has a problem with this package. If you are using the latest version, try the previous versions

  1. Open your terminal
  2. Go to your project directory
  3. Type the commands flutter clean then flutter run

I had a similar issue.

I had to go into my project folder and I renamed the "build" folder to "build.old" and the ".dart_tool" to ".dart_tool.old".

I was then able to run the command "flutter clean" from a command prompt at the root of my project folder.

As far as I can see, this happens when the build cache gets out of sync. To fix:

  • run flutter clean
  • delete the build folder
  • run flutter get

If this doesn't do the trick, try running flutter pub cache clean before the steps above.

It happened to me before i solved it by the following steps:

1- Updating the program
2- Updating flutter
3- Copying the files from old project to a new one
