I am new in flutter and I want to add Fast Android networking library to flutter dependencies and I don't know how to add, anyone, help me, please.
It is very simple to add a package in flutter dependencies. What you need to do is place it under the dependencies: inside the pubspec.yaml file.
So open the pubspec.yaml. You will find this file in root project folder of your flutter app. And do the following to add new dependencies/libraries:
dependencies:
flutter:
sdk: flutter
# dependencies come below here
example_dependency: ^3.2.0+1 // at the end is the version of the depenency
second_example_dependecy: any // 'any' for any version of the dependecy
To find or discover new libraries for flutter and dart to help you in building your app you can find flutter and dart packages here.
To add http package to your flutter project, from within a terminal at the project root, just type:
flutter pub add http
The latest stable version will be used.
For info on options take a look at https://dart.dev/tools/pub/cmd/pub-add

Flutter 3.3.9
I created a flutter project and I reference it as a dependency in another flutter project like so:
dev_dependencies:
flutter_test:
sdk: flutter
my_utils:
path: ../my_utils
When I added the local package to my project initially, I could see and debug the referenced local package just fine. I made updates to the my_utils package, did a "flutter pub get" in the project referencing my_utils, and the changes are not being picked up.
I added a new class to my_utils and it is not finding it in the other project.
I have this in analysis_options.yaml:
include: package:flutter_lints/flutter.yaml
linter:
rules:
depend_on_referenced_packages: false
Setting depend_on_referenced_packages to true didn't help.
How do I make my changes/updates in my_utils show in my referencing project?
Thanks
did you export the files properly ? e.g files inside src/?
my_utils file structure should be like the following:
lib/
...src/
......my_impl.dart
...my_utils.dart
and in your my_utils.dart should contain the following:
export 'src/my_impl.dart';
I recommend you use melos for managing multi-package projects. it might solve your problem. Also with melos bootstrap, you get flutter pub get running in all packages with one command.
you can follow the installation from here
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)
I have created a new flutter app and after adding cloud_firestore 0.13.0+1 it will not compile. No errors it just stops and removes the row of compile icons. An Analysing spinner revolves forever.
In pub.dev it says to "Migrate the plugin to the pubspec platforms manifest." unfortunately I have been unable to find out where that is or how to do it in the documents or StackOverflow. Please help.
According to documentation, the plugins you required need to be added under dependencies in to a pubsec.yaml file located in the root of your project.
dependencies:
cloud_firestore: ^0.13.0+1
After your plugins are added to pubsec.yaml, you can make use of those dependencies in your code by using imports.
import 'package:cloud_firestore/cloud_firestore.dart';
A few months ago I made an android application using flutter. The application requires various dependencies such as intl, cached network image, stopper, carousel_slider, etc.
Then right now I want to convert the project to flutter_web. Here are the steps that I did:
clone github web flutter
I run the command "flutter packages pub global activate webdev"
Then I edited pubspec.yaml and I adjusted it to pubspec.yaml in the previous project (android project)
Here is the contents of pubspec.yaml on the web flutter project:
name: flutter_web.examples.hello_world
environment:
# You must be using Flutter> = 1.5.0 or Dart> = 2.3.0
sdk: '> = 2.3.0-dev.0.1 <3.0.0'
dependencies:
flutter_web: any
flutter_web_ui: any
stopper: ^ 1.0.1
dev_dependencies:
build_runner: ^ 1.4.0
build_web_compilers: ^ 2.0.0
dependency_overrides:
flutter_web:
git:
url: https://github.com/flutter/flutter_web
path: packages / flutter_web
flutter_web_ui:
git:
url: https://github.com/flutter/flutter_web
path: packages / flutter_web_ui
provider:
git:
url: https://github.com/kevmoo/provider
ref: flutter_web
When I run 'pub dev', an error occurs while resolving the package stopper. Then I tried to open github from the package stopper (https://github.com/aryzhov/flutter-stopper), after that I checked the files in the lib folder. There I found a file called stopper.dart. It turns out that in the file, still using
import 'package: flutter / material.dart';
So that makes my pubspec error. Because the code should be replaced with
import 'package: flutter_web / material.dart';
Therefore, I tried to outsmart the problem by removing the dependency stopper on pubspec.yaml, then I created a stopper.dart file manually, then I saved it in the lib/mypackages folder. After that, I import stopper.dart from the lib/mypackages folder (it's no longer through the package).
The package stopper is just one of the packages that I use on my Android project. Actually there are many other packages that have the same problem as the package stopper. The point is I have to create the package files manually, then I change "package: flutter / ..." to "package: flutter_web /" manually, then I can import them.
What I want to ask, is there a more elegant and simple way?
Hi the instruction you are following is from an old repository here. As you can see this is discontinued. You can find the informaiton in the REadme.
Instead you should follow the instructions in this page. Read it once carefully and I would suggest to keep a backup of your main project and work on a copy.
First you will have to enable the flutter-web using flutter config --enable-web.
Then you will have to run flutter create .
What would be the best practice to test the working of flutter package?
Recently I developed a Flutter package and I am testing its functionality by creating another flutter application and importing it to there, in this way I have to deal with two projects. Is there any method to do all it in the same project like android native development?
example/ directory contains only example.dart which is not runable? Any suggestion ?
Answer based off of Shahzad's flutter_tex package, and thanks to Remi's suggestion.
As mentioned, one way to test a package in Flutter is to create a Flutter app within the "Example" directory. In this app, list the following in the pubspec.yaml file:
dependencies:
flutter:
sdk: flutter
your_package_name:
path: ../
As shown, you specify your package's path, which is the level above the "Example" folder the test app resides in.
