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

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 want to install a simple audio recorder which will record a user’s voice. I know I can find plugins on PubDev, however I have difficulty in integrating them into my Flutter project. I have installed ‘audio_recorder 1.0.2. in a new dart file as part of ‘lib’. I don’t know how to integrate this file into the flutter project. I have tried to a button in another dart file which when pressed would take the user to that file, without succes. ‘This class is not a widget’ is the message I get. The ‘GitHub’ version has the errors ‘undefined class’, ‘LocalFileSystem isn’t defined for the type ‘AudioRecorder’. The example version (why this difference?) has quite a few errors after installation. Dependencies and imports are ok. When I install audio_recorder 1.0.2 inside the project via ‘Dart packages’ I get a lot of errors. I have successfully installed an audio recorder in another android app. I would like some help in how to integrate plugins in a flutter project.
The plugins have instructions on how to install it. Got to your pubspec.yaml-file and put it under dependencies.
Make sure that you add your dependency to pubspec.yaml like this:
dependencies:
audio_recorder: ^1.0.2
After that make sure to type "flutter pub get" in console.
Go on a specified file in which you want to use Your dependency and import it like this:
import 'package:audio_recorder/audio_recorder.dart';
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'm slowly building my personal website over at dlblack.dev, and I'm trying to spice it up a little bit. For example, from a computer (rather than a tablet or phone since they don't have mouse pointers), if you hover over any of the clickable items, it doesn't change your mouse pointer to indicate it's clickable, and the clickable object doesn't change at all. I've decided to follow this FilledStacks tutorial, but it doesn't mention anything about fixing this problem.
Essentially what's happening is when I get ~2.5 mins through the tutorial video (where he writes the skeleton extension class) and try to duplicate it, VS Code redlines almost the entire class declaration aside from the name. What I'm writing is the exact same thing as what he has on screen at 2:26, and here's my code:
import 'package:flutter/material.dart';
import 'dart:html' as html;
extension HoverExtension on Widget{
}
"extension", "on", and "Widget" are all redlined when I do this. When I hover over "extension", it says the following:
Undefined class 'extension'.
Try changing the name to the name of an existing class, or creating a class with the name 'extension'. dartundefined_class
This requires the 'extension-methods' language feature to be enabled.
Try updating your pubspec.yaml to set the minimum SDK constraint to 2.6 or higher, and running 'pub get'. dart(experiment_not_enabled)
The first thing I did was change my minimum SDK constraint to 2.6.0 in my pubspec.yaml file. I then changed it to 2.7.0 because a lot of people online say extensions were released in Dart 2.7. I've done a lot of Googling on the subject but no one seems to have the same problem as me: I have no analysis_options.yaml file. I created one, and put only this in its contents:
include:
analyzer:
enable-experiment:
- extension-methods
linter:
In theory, I believe that should fix my problem once I run flutter pub get from the command line in my root folder; it doesn't. I have no idea what's wrong. Any suggestions?
In Android Studio solving this problem requires three steps:
Update SDK version in pubspec.yaml (must be 2.6.0 or higher)
environment:
sdk: ">=2.7.0 <3.0.0"
Tools -> Flutter -> Flutter Clean
Close project and reopen it (eg. File -> Close project)
For the changes in pubspec.yaml and analysis_options.yaml to take place, you have to restart the Dart Analysis Server. In VSCode, that's as simple as Ctrl+Shift+P -> Reload Window.
I had to do flutter clean, then close and re-open VSCode.
I had a similar problem with the "extensions" feature in Dart (on Windows) ... I was getting "undefined class", and the message saying that I needed to use the "experimental" Dart settings. It seems that I had two Dart installations, one in "c:\Program Files" and one in "c:\tools\dart-sdk". I removed the version under "Program Files". I also ran "choco uninstall dart-sdk" and "choco install dart-sdk", and made sure that the version was correct (using "dart --version") after the install. The command "where dart" should display "c:\tools\dart-sdk-bin-dart.exe" after the choco install. When I went back into my Flutter project (using Android Studio) it said that I didn't have Dart support for my project, and I just had to enter the Dart SDK location.
if tombroz's solution won't work then
1.Tools -> Flutter -> Flutter Clean
2.Tools -> Flutter ->Pub get
3.File -> Invalidate cache/Restart -> Invalidate cache and Restart
I just had to run flutter clean et voila.
When I run
flutter pub outdated
it gives me a list of all the packages I have in pubspec.yaml which are outdated. What if I have more than 100 packages in it, I'd like to know is there any command or way (except searching in terminal) to find out the information provided by above command but only for that package, something like:
flutter pub outdated xyz
where xyz is my package.
For Android Studio and IntelliJ, use Flutter pub version checker
For Visual Studio Code, use Pubspec assist
There is this plugin for Android Studio called Flutter enhancement suite which automatically detects outdated packages and suggests updates for you inside pubspec.yaml file
