Error setting-up flutter_localizations package "Target of URI doesn't exist: 'package:flutter_gen/gen_l10n/app_localizations.dart'."

Question

This error appears when I try to add language support to my flutter application:

Target of URI doesn't exist: 'package:flutter_gen/gen_l10n/app_localizations.dart'. Try creating the file referenced by the URI, or Try using a URI for a file that does exist.

I’m using flutter_localizations, the project is built with dart 2.7.0

It seems that flutter_localizations needs latest sdk which is dart 2.13.0

How can I fix this?

Answer 1

I had this same issue with import 'package:flutter_gen/gen_l10n/app_localizations.dart' in Visual Studio Code after updating to Flutter 2.5.

After closing the VS Code window and reopening it, the error was gone. If that doesn't work, try closing and opening VS Code again.

Or restart the Dart Analysis Server by going to View > Command Palette and then typing Dart: Restart Analysis Server.

Answer 2

Just type in the project terminal flutter gen-l10n it will solve your problem.

This works on my case. I'm using VSCode. – Schmaltz

Answer 3

The solution in my case: "If you are using a package flutter_gen you need to remove it from pubscpec.yaml to resolve conflict." credit Target of URI doesn't exist: 'package:flutter_gen/gen_l10n/gallery_localizations.dart'

Thanks @giorgio79. That was the issue for me. In my case, I added flutter_gen package to the dependencies instead of adding flutter_gen_runner to dev_dependencies. – Culex

Answer 4

Open Command Palette and select Dart: Restart Analysis Server.

Answer 5

Also, in the pubspec.yaml file, enable the generate flag. This is added to the section of the pubspec that is specific to Flutter, and usually comes later in the pubspec file.

# The following section is specific to Flutter.
flutter:
  generate: true # Add this line

Answer 6

I had this issue before, and I tried to solve it by adding charts_flutter to my pubspec.yaml but it didn't solve my.

Lucky me, charting library recently released a new version which is compatible with flutter 2.5. I didn't need to add anything to my pubspec(I removed chart_flutter from my ). just run the app even if the compiler shows an error saying Target of URI doesn't exist for the import line. The system is going to generate that file on runtime.

Answer 7

Be sure that there's an l10n.yaml file in your project root as follows.

Example

Demonstration variables

foldername = l10n
defaultIntlFile = intl_en.arb
importFileName = app_localizations.dart

Import

import 'package:flutter_gen/gen_l10n/importFileName';

l10n.yaml

arb-dir: lib/foldername
template-arb-file: intl_en.arb
output-localization-file: app_localizations.dart

Structure

lib/foldername/defaultIntlFile

You can restart Dart Analysis Server and the issue will be resolved.

If you use VS Code:

View -> Command Palette -> select Dart: Restart Analysis Server.

If you use Android studio:
