3. On terminal write flutter clean and then flutter run

Answer 2

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!

Answer 3

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.

Answer 4

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

Answer 5

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

Answer 6

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.

Answer 7

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.

Answer 8

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
