By updating Flutter 3.8.0
I am getting the following error in flutter_date_time_picker.
I would like to know if anyone knows a solution to this problem.
../../../../.pub-cache/git/flutter_datetime_picker-eb66486c47d50bf550950c196486121ffcea8885/lib/flutter_datetime_picker.dart:7:1: Error:
'DatePickerTheme' is imported from both 'package:flutter/src/material/date_picker_theme.dart' and'package:flutter_datetime_picker/src/datetime_picker_theme.dart'.
pubspeck.yaml
flutter_datetime_picker:
git:
url: https://github.com/Realank/flutter_datetime_picker.git
If anyone knows of a solution, I would love to hear about it.
I believe this is probably due to the flutter update, as I was able to build normally until yesterday!

You can try the following steps:
Remove the flutter_datetime_picker package from your pubspec.yaml file.
Run flutter clean in your terminal to remove any cached files.
Re-install the flutter_datetime_picker package.
first try to flutter clean and then pub get and reinstall the package you want. if again you had this error try this:
To resolve it; in the class where you have both imports, assign an alias to one of the packages using the as keyword.
import 'package:flutter/src/material/date_picker_theme.dart' as dp
dp.EveryMethodYouWant(); //call the class using the alias
if you had any question i'm here.
happy coding.
By mistakenly,you have imported the wrong package because as per the package documentation, there is no such line mentioned.
Import the package mentioned below and try pub get.
import 'package:flutter_datetime_picker/flutter_datetime_picker.dart';
everything vill works fine.
Is there a way to make Android Studio auto import packages from external libraries?
What I mean by that is I got to pub.dev getting package I want and then in Android Studio I can write name of the class I want to use from that package and IDE would auto import it for me... I believe in VS Code is as simple as on mac cmd + . (fullstop) is driving me nuts
thank you
yes, you can add any external package from pub.dev using this command in terminal:
flutter pub add package-name
In my flutter project structure settings, the android studio gives me this problem:
Library Dart Packages has broken classes paths: $home/snap/flutter/common/flutter/.pub-cache/hosted/pub.dartlang.org/path_provider_macos-2.0.2/lib [Fix]
Removing this folder and repairing the cache using dart pub cache repair does not help.
This package path_provider_macos-2.0.2 does not have a lib folder even in their repo - https://github.com/flutter/plugins/tree/master/packages/path_provider/path_provider_macos
Every other dart package has that essential lib folder. Maybe it's the package error?
Does anyone know how to fix this?
After a quick look, it seems that using this package is not necessary. As seen in the image below. Therefore I think using path_provider itself should also work for MacOs
Greetz!
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?
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.
Credit goes to https://stackoverflow.com/a/68150402/4797855 and https://stackoverflow.com/a/68731436/4797855.
Open Command Palette and select Dart: Restart Analysis Server.
Just type in the project terminal flutter gen-l10n it will solve your problem.
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
just in Your terminal run this
flutter pup add flutter_gen/gen_l10n
It fixed my app
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.
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
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'
I tried using the simple_permissions plugin and then I got an error to migrate to androidX even though I had migrated to androidX and after I deleted android.Jetifier at gradle.property I didn't get any more errors and the plugin was successfully used. Why did it happen? Will my project get a problem in the future? Thanks!
Make sure that all your packages in the pubspec.yaml are of the latest version. Then open the android project of your flutter app with android studio, select Refactor->Migrate to Androidx. Wait until android studio finishes migrating your project, rebuild your project. Hope it helps!
