Invalid depfile: Flutter

Question

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

Did you try the command "flutter pub get" ? Because it looks like one of your packages is not found. – Ecumenical

Answer 1

Okay so I found out since I changed the PC, I needed to change permissions of a file. Follow here https://github.com/simolus3/moor/issues/224

Peipeiffer

Answer 2

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';

Pinnace

works like charm, why the html make this error? – T

In my case, I need to remove import 'dart:js'; – Gon

Thats horrible, I checked my code and accidently I also imported dart:html, after deleting unnecessary import its solved. thank you – Faustinafaustine

Hmm, how do I identify which import is affected? I neither have any "dart:html" nor "dart:js" imports. – Commove

Answer 3

I got the same error and I am following a udemy course as well.
I tried flutter pub get and it worked.

Orth

Answer 4

i also faced the same problem and i sort out by running "flutter clean" command. https://github.com/flutter/flutter/issues/21053

Answer 5

Invalid depfile: D:\...\f5\.dart_tool\flutter_build\8e234dd4da26339b660f6097cc2a271a\kernel_snapshot.d

Delete kernel_snapshot.d and kernel_snapshot.stamp files at this location:

your flutter project\.dart_tool\flutter_build\8e234dd4da26339b660f6097cc2a271a

Guthrun

This worked for me but I still want to know the reason behind this. – Unstick

Answer 7

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

Meliorate

Answer 8

I have the same bug and I deactivated vs code. When I reactivated it, I just typed

flutter clean

flutter pub get 

flutter run

And everything started to work.

Uredium

Answer 9

well, you can do two steps to fix this issue

1. flutter clean
2. flutter pub get

after running these commands it should fix your issue

Okeechobee

Answer 10

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

check again please and till me – Jackquelin

Thanks. In my case, it is this file that was imported which was causing the error: import 'dart:js_interop'; I removed it and everything was fine. – Moeller

Answer 11

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.

The build error I got:

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.

Answer 12

This happened to me, try to delete unused imports in your project!

Diabolo

Answer 13

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

Answer 14

If you're on VS code "try flutter clean then flutter run" on terminal

Answer 15

Fixing problems in "Dart Analysis" tab solved the problem

Sculpturesque

Answer 16

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.

Answer 17

I figured that out the issue was caused by import 'package:firebase/firebase.dart'; in my project to Fix it delete that import

Hexamerous

Answer 18

In my case, I had the same problem and solution:

flutter clean . 
 

flutter create .

This is a solution that I always try before almost any problem, then if it is not solved I see it in ..

Garrulity

Answer 19

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.

Optimistic

Answer 20

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';

Henceforth

Answer 21

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.

Rachal

Answer 22

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.

Livesay

Answer 23

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

Controversy

Answer 24

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.

Answer 26

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.

Hope this helps.
