Asset files which referenced in pubspec.yaml are too big. I want to keep only fonts which used in the project.

flutter_icons/fonts/MaterialCommunityIcons.ttf
flutter_icons/fonts/FontAwesome.ttf
flutter_icons/fonts/FontAwesome5_Solid.ttf
flutter_icons/fonts/FontAwesome5_Brands.ttf
flutter_icons/fonts/Ionicons.ttf
flutter_icons/fonts/MaterialIcons.ttf
flutter_icons/fonts/weathericons.ttf
flutter_icons/fonts/Entypo.ttf
flutter_icons/fonts/AntDesign.ttf

flutter_icons/fonts/Feather.ttf
flutter_icons/fonts/Zocial.ttf
flutter_icons/fonts/FontAwesome5_Regular.ttf
flutter_icons/fonts/Octicons.ttf
flutter_icons/fonts/EvilIcons.ttf

If I request an Icon which does not exist IconData gets returned anyway with the codePoint = null. This leads to a weird flutter assert which has nothing to do with the IconData and it is hard to track. Could u please just return null or throw an exception

IconData data = MaterialIcons.getIconData(key);

Getting errors related to null safety support Error: Cannot run with sound null safety, because the following dependencies don't support null safety:

**Please do migrate the package to null safety **

Is it possible to access all icons with a single API? For example, I want to select the best looking calendar icon from all of the sets. But, I have to type the name of all sets one by one and add dot calendar after them. If all the icons are accessible from a single class it would be easier to select the best calendar icon.

Thank you for the great package.

Hi folks.

First of all I want to thanks you. I'm currently using this package and it's great! :)

I was wondering if it makes sense split this package into several subpackages in order to optimize application size. In my case I'm just using MaterialCommunityIcons. AFAIK I have to import the whole package, including the other .ttfs & resources, increasing the total size.

Is this possible? Do I am wrong assuming that all resources are bundled into the release builds?

Regards.

All Icons should be searchable in one list to search all libraries - copy and paste should work to get the names to copy them. Also, the search icon has to be clicked to start a search. Search should be triggered by just typing. The Chinese string in the search field does not work with most of the world. Could you change it to English to make it more comprehensible ( I am German ) ?

I like the package - don't get me wrong.

It would be cool to have an easier Interface as an extension to your package which allows the extraction of the Icons like this:

///searches all libs and returns the first finding
IconData data = IconCache('altimeter')
///searches only Material Icons 
IconData data = IconCache('altimeter', IconLib.mdi)
///searches only Material Icons 
IconData data = IconCache('mdi.altimeter')
 

all methods return a default icon if no Icon is found (could be changed to null). This addresses #12

Here is the implimentation:

import 'package:flutter_icons/flutter_icons.dart';

I am wondering if by using this Library dart/ flutter tree shaking still works or if all Icons are loaded in memory because I can access them with an indexer (map)?

FYI Tree shaking. In computing, tree shaking is a dead code elimination technique that is applied when optimizing code written in ECMAScript dialects like Dart, JavaScript, or TypeScript into a single bundle that is loaded by a web browser.

Hi, thanks for wonderful icons!

the icon preview from website, is not same with I set in flutter app:

As you can see, the grin icon it not solid, while website is like this:

I want it to be solid so that fits the style of my app. Do u know why it's not same?

Hi, first, thanks a lot for this project.

In the Readme, it says this project it's inspired by react-native-vector-icons. And then I checked https://github.com/oblador/react-native-vector-icons, it says MaterialIcons is from https://www.google.com/design/icons/. Then I checked https://www.google.com/design/icons/, it redirects to https://material.io/tools/icons/. Then I searched for home-outline icon, I found the result at https://material.io/tools/icons/?search=home&style=outline. BUT from the latest project code flutter-icons/lib/material_icons.dart, I can not find home-outline at all.

Thanks.

Is this package alive? I thought it would be really useful for my app but none of the icons is working. example: Icon(WeatherIcons.wi_cloudy) or any other icon is not working. All i'm getting is a box kind of looking thing.

9cf4b48 fixes the majority of the analyzer warnings (mostly redundant const declarations).

0889610 migrates the package to null safety.

Notes:

• author pubspec.yml attribute is no longer supported.
• Major version bump is recommended by the official migration guide to indicate a breaking change.

Please consider this PR for release, because the package complicates migration to null safety for the apps that using it.

Fixes #41. Fixes #45. Fixes #46.

Bug info

Can't Find Some icons, especially Ionicons. Some Icons I noticed to be missing are
* Ionicons.ellipsis-horizontal-circle
* Ionicons.ellipsis-horizontal-circle-outline
* Ionicons.paper-plane-outline
* Ionicons.ios-paper-plane-outline
* MaterialIcons.all-inbox

https://simpleicons.org/

They have npm integration already at https://www.npmjs.com/package/simple-icons

MaterialDesignIcons no longer accepts Brand Icons http://dev.materialdesignicons.com/roadmap/brand-icons

2. BrandIcons They already have a Flutter package at https://pub.dev/packages/flutter_brand_icons
