myicons | Your flat icons manager and font builder | Icon library

Let's say I have icons:

I'm new to flutter/dart and trying to create a learning project. I needed a list which I first added in main.dart but then separated it with another class. I've 3 files now

1. main.dart
2. icon.dart
3. mid.dart

main.dart:

I want to add an Icon to a List following UI update using flutter Provider state Management. I was successful to add an Icon using the floating button and confirm the result by printing the new List length. This ensures the addition of an Icon to a List but it does not update the UI for the new added Icon. Snippets are below

In short, I want to make a collection of icons in a GridView from which the user can select one to change their profile icon.

I'm thinking that I can achieve that by declaring the icons I need on a ResourceDictionary

I'm working with react Bootstrap. I have designed a layout which I want to refactor on small screens. All I want to do is, at certain breakpoints I want my h3 elements and image resized. I've been using the following:

Code from index.css :

React Native rookie here. I am trying to adjust the React Native expo tabbed app to my learning needs. I am currently working on Flatlists and I want to open a new screen on ressing any item of the FlatList sending as parameter on of the item's props. I have reached a certain point but can't seem to successfully complete it.

I am trying to create a FlatList and set leftAvatar image based on the value of my fetched JSON and my const JSON. My example:

How can I programmatically create a list of objects of the leaflet icon class?

I have created a map using the leaflet library that will eventually show dozens of locations. For this I want to add some custom icons using the addMarkers function, which takes an iconSet created using iconList as documented here.

In the example below (which uses icons from https://icon-library.net/), the creation of myicons by means of iconList, which contains two direct calls to makeIcon, is unproblematic because only two icons are used. However, in the real world the number of icons, their URLs and other attributes will not be known in advance.

If create a list using iconList and use cbind to attach it to the data frame as a new column, I get the expected "cannot coerce class" error message.

My only option appears to be to programmatically create the myicons list, but using something like mynewicons <- iconList(sapply(1:nrow(df.data), function(i) {makeIcon(df.data$url[i],iconWidth = df.data$width[i],iconHeight = df.data$height[i])})) results in an Arguments passed to iconList() must be icon objects returned from makeIcon() error.

How can I create this list of leaflet icons dynamically rather than specifying it in advance?

In today's fractured web-icon landscape where (surprisingly) .svg icons have not yet achieved broad support, one might be tempted to add a huge list of elements in the head pointing to any number of

• favicons
• icons
• apple-touch-icons
• safari-pinned-tabs
• mstiles

etc.

A comprehensive list of favicons, icons, touch-icons, tiles etc. on any page would be enormous.

This affects page initialisation and loading time, in some cases quite dramatically.

The goldilocks solution would be to be able to add as many icon references as needed, without affecting page load performance.

So... is it a legitimate approach to load these elements asynchronously?
