i have an error in initState importing doesnt package doesnt work
error in flutter native splash
Did you imported the package using import at the top? if so then check the version compatibility of package with your flutter version. If you've just added this package, try flutter clean and flutter pub get.
There is no Show() method on Flutter Native Splash. I advice reading the instructions on how to use the package.

Getting this error for build failure:
error build: ../../../development/flutter/.pub-cache/hosted/pub.dev/bubble_bottom_bar-2.0.0/lib/bubble_bottom_bar.dart:195:14: Error: ‘Badge’ is imported from both ‘package:badges/src/badge.dart’ and ‘package:flutter/src/material/badge.dart’.
Using code from https://codecanyon.net/item/flyweb-for-web-to-app-convertor-flutter-admin-panel-v10/26840230
Can anyone suggest where and what needs to be edited to get this issue resolved.
Have tried updating the Flutter with following commands
Flutter clean
Flutter pub get
Have also reinstalled pods for ios and still failing to build on Flutter build ios
Badge is coming from both material and badge package. Flutter material provide by default.
If you wish to use the package one, you can do
import 'package:badges/src/badge.dart' as badge;
Now to use it, call badge.Badge(....
I'm working with Firebase in flutter (latest versions as of 1st July 2022), and when I try to call Firebase.initializeApp() in my Main function, it returns an error of:
'[ERROR:flutter/lib/ui/ui_dart_state.cc(198)] Unhandled Exception: PlatformException(channel-error, Unable to establish connection on channel., null, null)'
Here is my code:
void main() async {
WidgetsFlutterBinding.ensureInitialized();
Firebase.initializeApp();
runApp(const MyApp());
}
Any help would be greatly appreciated
I was able to solve the problem by upgrading all my firebase dependencies to the latest version using flutter pub outdated and flutter pub upgrade firebase_....
I encountered this issue after adding the firebase_messaging plugin v11.4.4. Might be related to the change in firebase_core_platform_interface.
Also got it after a pub update. Fixed it by doing:
flutter clean
and removing the pubspec.lock
Do a flutter clean and upgrade firebase core with
flutter pub upgrade firebase_core
The run
dart pub global activate flutterfire_cli
flutterfire configure
to reinitialize firebase. I experienced this after adding app_check support
I have updated the below dependency:
dependency_overrides:
firebase_core_platform_interface: 4.4.1
Executed this command and updated firebase dependencies
flutter pub upgrade firebase_core
flutter pub upgrade firebase_messaging
it is working properly now.
Problem seems to be with the core platform interface.
Add firebase_core_platform_interface: 4.4.0 and adjust all other firebase deps to make them compatible with this library. I downgraded all versions to 36 day old release and it finally works.
I just built a new flutter app and I got this error when initializing Firebase App and running it in the browser and not the android emulator. I am using VS Code and you can change the target device in the bottom task bar on the right side.
Solution is to run it in the android emulator. I don't know if there are permissions to be set for web view but I do not plan on deploying to web.
Had the same problem and scaled back (thank you git) - getting flutter dependencies right - as in it compiles and work as advertised is no mean feat. Welcome :)
My flutter has suddenly started giving me this error on assets_audio_player : "Undefined class 'AssetsAudioPlayer'.". The import for the player: import 'package:assets_audio_player/assets_audio_player.dart'; is also greyed out. I've tried upgrading the flutter & restarting the device but the issue is still there. Any clue what might've gone wrong? Thank you!
Before importing the package in your code, did you properly add its dependency in your "pubspec.yaml" file and then run the flutter pub get command?
I am guessing you're using this package.
Be sure to add a line like this to your package's pubspec.yaml (and run an implicit flutter pub get).
dependencies:
assets_audio_player: ^3.0.4+1
Im new to Flutter, i use Visual Studio Code with Flutter extension. I try to import the package "font awesome" but i got an error. I search on internet but nothing solve that.
Error
pubspec.yaml
Flutter pub get
Import package
If still not importing then restart IDE
hope this will work
If you run flutter pub add font_awesome_flutter or flutter pub get font_awesome_flutter and the import statement still shows an error, try running flutter pub upgrade font_awesome_flutter.
I started fluttering a few days ago. I want to add "font awesome" to my project, but I can't. I searched but could not find the right answer. I finally got this guide, but it doesn't work either.
Adding a package dependency to an app
To add the package, css_colors, to an app:
Depend on it
Open the pubspec.yaml file located inside the app folder, and add css_colors: under dependencies.
Install it
From the terminal: Run flutter pub get.
OR
From Android Studio/IntelliJ: Click Packages get in the action ribbon at the top of pubspec.yaml.
Import it
Add a corresponding import statement in the Dart code.
4. Stop and restart the app, if necessary
If the package brings platform-specific code (Kotlin/Java for Android, Swift/Objective-C for iOS), that code must be built into your app. Hot reload and hot restart only update the Dart code, so a full restart of the app might be required to avoid errors like MissingPluginException when using the package.
In the dependencies: section of your pubspec.yaml, add the following line:
dependencies:
font_awesome_flutter:
Look here https://pub.dev/packages/font_awesome_flutter/install
It contain examples and instructions.
Steps also the same:
add the package name to dependencies section. It very important to keep the correct number of spaces in every line of pubspec.yaml, it has very sensitive format
in your case:
dependencies:
font_awesome_flutter: ^8.10.0
Click "Packeges get" in top right corner
Import the package into your dart code
in your case:
import 'package:font_awesome_flutter/font_awesome_flutter.dart';
Now your can use it in Icon widget
Icon(
FontAwesomeIcons.mars,
size:80.0)
