Invalid depfile: Flutter

I am following a tutorial from a udemy course and recently I built a new pc so the hard drive that stored my code is secondary right now. When I compile the code, it gives me the following error. To explain it better, I am posting a picture of one warning in my code but I am pretty sure it is an error flutter is making as it usually does with imports. Error in Code I have tried running a test app by making a default app from cmd and that works fine. So obviously, flutter doctor shows no error. the error is repetitive and long so I am pasting some of it below.

The error-

Invalid depfile: D:\WorkSpace\Code\Flutter\Image App\image_app\.dart_tool\flutter_build\8f0d0eee9ef614ed024ca7691a333af8\kernel_snapshot.d

In my case i updated my flutter version and had to update my intl v0.19. here are the steps i took to solve my issue. I wasnt interested in using flutter Localization so i deleted the l10n.ymal.

After thus run: flutter clean && flutter pub get

Hope this helps.

check your code properly, dart may have automatically imported some packages that are not necessary. check your imports very well, remove all imports not that are from you. In my case this was the import that was causing the error

"import 'dart:nativewrappers/_internal/vm/lib/ffi_allocation_patch.dart';"

I removed it and my code started working again.

While you are writing the code, this library is import by itself. ( import 'dart:html';)This causes some problems. You can delete it from the code

Before running 'flutter pub get'

Go to the dependencies folder e.g. or whichever your app is pointing to ...

C:\Users\Administrator\AppData\Local\Pub\Cache\hosted\pub.dev

Look for the dependency that is misbehaving and just delete it.

Then run 'flutter pub get' to re-download it

flutter pub get

It's easy. The way around it is to look on the home page or the main page, comment out or delete the 'import dart.html' and save, and then run flutter run. You should be good to go.

I face similar problem I solved it by deleting import 'dart:html'; from top of the dart file. i.e remove import 'dart:html';

Someone has a solution to delete kernel_snapshot.d and kernel_snapshot.stamp

Well, I did but error not gone. What i did else is to check other errors and other errors was coming from Stripe Package. So i commented like this #flutter_stripe ^2.1.1 on pubspec.yaml and also, do Pub get: Note : Any error you see after commented or removed sdk package on pubs make sure you remove those errors else, after that, clean build folder on xcode and run pod install. The error gone. For you and anyone else, check other errors below the red or yellow highlight on Xcode. You may see other error which may not shown on Buldtime Nav. also make sure you use the latest Xcode Version.

Like many of you have suggested, I tried out almost all the things mentioned here and several other StackOverflow posts. But nothing worked for me.

Could not build the application for the simulator.
Error launching application on iPhone 12 Pro Max.

One of the solutions that looked promising was deleting two files; kernel_snapshot.d and kernel_snapshot.stamp however that also didn't work for me. But I went to the path where these two files were residing. You can have a look into the folders and files structure in the following screenshot:

So what I did is actually delete those files that have been selected in the following screenshot and then try running the app as usual on the simulator. And it worked.

Check for any import which is related to browser or http and if your target platform is mobile then you might not need browser import and you can remove it.

In my case, I have removed this.

import 'package:dart_web3/browser.dart';

Take a closer look if you have added such an import?

    import 'package:firebase/firebase.dart';

If so, this is for the web. If you are writing a mobile application, then it is better to use such an import :

    import 'package:firebase_auth/firebase_auth.dart';

This could be a potential error.

Sometimes it happens to me too. I either deleted the converted code or converted it command For example here I entered:

import 'dart:html';

, And my error was fixed after deleting it or turning it into a comment

// import 'dart:html';

I had exactly the same error and later on came to find out that I had imported web-only dependency in my pubspec file.

In my case.

firebase: ^5.0.0

This is only for web.

I experienced this. At first you have to check if you added the related dependencies on the pubspec.yaml file like below:

web_socket case ==>

( on pubspec.yaml )

dependencies: web_socket_channel: ^1.1.0
flutter: sdk:flutter
