I have successfully installed the Flutter plugin to Android Studio on my Windows10 system, and flutter doctor -v gives me all green check marks.
However, the DART examples from pub.dev fail to compile with the error message that libraries must be added to the file 'pubspec.yaml'.
Where is this file? As shown below, no such file appears in the project hierarchy?

This is a default folder and file structure of a Flutter project. In your case pubspec.yaml file isn't present, which should be there. So I think this is an issue related to build. So just try to rebuild the project, and it should be cured. Just Open terminal on the Project folder and run the following commands.
flutter clean
flutter create <Exactly same project name>
This should rebuilt the project.
If this is a new project and you haven't done anything on the project yet, I will suggest to create a new project using terminal commandline, as according to me commandline with VSCode is the best way to work on flutter (Obviosusly it's based on preference).
I tried to import flutter project from my pc to the android studio and got this error.
I already read the link that they give to me but I still don't understand. A little help please, or how do I import flutter project correctly?
The error
The project is not Gradle based can be because bulid.gradle and settings.gradle are not in the IDE project directory,
Try this
Open that other folder as an Android Studio Project and let it download other dependencies and file or you can create new flutter project and check the file generated with yours and try to add the file not in your own from the new flutter project you created.
This will solve the issue
from which version/tool you imported the project?. This is normally happed because of gradle-wrapper issues. Please check the link.

I usually solve this by File -> Repair IDE
I created a new flutter project in android studio, but in the new version, I don't know where to find the main dart tab.
reference
You can find out main.dart in lib folder
You have to open the lib folder inside the lib folder you will get your main. dart file.
So I've been trying to use the HERE sdk for flutter, but whenever I add the unzipped file to the plugins folder and add it to the pubsec.yaml it gives me this error:
error
Here is my project directory for the plugins folder:
directory
I feel like I'm doing something really dumb, but I would appreciate any help.
Looks like the folder structure is not as expected. If you follow the quick start guide, you need to identify the plugin folder:
Unzip the downloaded HERE SDK for Flutter package. This folder contains various files including this documentation.
Inside you will find a TAR file that contains the HERE SDK for Flutter plugin.
Now unzip the plugin, then rename the folder to 'here_sdk' and place it to the plugins folder inside the example app's directory.
So, you need to unzip the package and then again inside the package you need to unzip the TAR (containing the plugin).
Unable to run flutter from Android Studio not detecting flutter project its shows Error: Entry point isn't within the current project
Every time restart android studio same error message shows
Delete the .idea folder inside the root of the flutter project and restart Android Studio.
Refer to this question: What is the .idea folder? and make your decision if it's safe or not to delete .idea folder.
Click on File-> Project Structure -> Module then add root folder of
your project then it will detect its a flutter app and then build and
work
its work for me
Reference: https://github.com/flutter/flutter-intellij/issues/2307
1) make sure flutter and dart sdk paths are properly configured from
File-> Settings..->Languages and Frameworks
as well as make sure Dart support is enabled for project module from Dart Option
2) at the end select File->Invalid caches and restart
3) so after 2nd step you may get in File->Project Structure.. option from there Select Modules then just simply add only root folder path of your flutter project and repeat just above 2nd step
for me this worked
Syncing your project with gradle files will solve it:
You can sync the files with Gradle, within the File menu.
Else You can re-include the files/project root folder inside the File Menu.
File -> Project Structure -> Module
And then add the root folder of the project(with + icon), then it will detect that it's a flutter app again, and then build and work again.
Try delete .idea folder inside project folder and Invalidate & Restart Android Studio.
For me my project was missing the pubspec.yaml file, it was deleted by mistake , instead of warning about the missing file , I got this error
This problem happened to me
I solved it this way
Go to the Android Studio track
I have this way
C:\Users\mustafamaxL\.AndroidStudio4.0\system
Remove folder (caches)
Then, start Android Studio again
If your ios, android, or lib folders are missing, it typically means there is something wrong with your project structure.
To fix it, delete the .idea folder in the root of your project and then restart Android Studio. If you're using a Mac, you can display the hidden .idea folder by pressing Command+Shift+Dot in Finder.
The .idea folder will be automatically regenerated and everything should be back where it belongs.
See this post for the original solution.
Click Content Root Close Icon and Remove Android Folder.
Fix it to me.
I faced the same issue today and tried other solutions here but it wasn't worked at all.
In my case I deleted three folders that is android, ios, and .idea from project directory, then restarted android studio and finally I gave this command in Android Studio's Terminal.flutter create . to create appropriate directories (i.e., android & ios).
Now it is working fine.
Note: Before deleting the android / ios directory please make a backup of these directories only if you previously gave native code in android / ios directory.
Hope this solution will helpful if others will not work.
The .idea folder will also be deleted on Linux. When Andriod Studio opens, click terminal at the bottom in Android Studio. Then type remove -r .idea/ in the terminal and press enter. After deleting, close and restart Android Studio.
You might need to update the Gradle version. Or change the minimum android SDK version.
Here is worked for me:
Update Gradle / minSdkVersion version
Reopen the project but at the directory user/StudioProjects/yourFlutterApp/android.
After it is opened it will load some packages (see right bottom), which will take some time.
It will ask you to update the Gradle version (right-left corner) or go under File>Project Structure Project you can set a higher Gradle version and under Modules variables of your build
Now you can sync your project with Gradle files
After configuration, you might need to restart your project with File>Invalid Caches/Restart....
I have created 2 folders inside lib's folder for my *pages* and *widgets*.
Getting the main.dart file back to the **lib folder** will do the trick
I'm currently in Android Studio Electric Eel.
I've done all of the suggested solutions above, but nothing works.
Turns out the project is not detected as a Flutter project. So what I do to resolve this issue is to remove gradle-related files from the root folder:
build.gradle
gradlew
gradlew.bat
gradle/
