How to use own icons in Flet - icons

I can't find how to load my own icons in Flet.
I'm testing Flet with the intention of making a desktop app (pure desktop, not Internet needed), but I'm not able to use my own icons to begin with. I can only use the ones that come inside ft.icons, but I'd rather use my own by loading them from a folder similar to /assets/icons. Can I do that? How?
Thanks.

Currently, I don't see a way of doing this; however, you could use the Image class instead.
I would suggest you create an assets folder under your main project folder.
Let's assume you have the following folder structure on your project:
/assets
/icons/my-icon.png
main.py
When you are running your app, you should provide that folder to the initializer in the following way:
flet.app(target=YourApp(), assets_dir="assets")
Then you can access your images there directly and create an Image instance in the following way:
test_image = flet.Image(src="icons/my-icon.png", width=32, height=32, tooltip="Image Tooltip")
You can nest these Image controls inside of anything you want, so you have a lot of flexibility.
The only downside of doing it this way is if you are using light/dark themes on your app. Compared to the Icon class, you will have to specify the light/dark theme versions yourself and update them manually when you are switching your theme.
Here is the official documentation

How to use images in CSS code inside an Angular library

I've built a library that will be used by several Angular applications (multiple teams and no monorepo). This library includes a scss-theme. This theme uses two SVG-files. However, I can't get it to work. The path is always incorrect.
My theme scss:
.test::before {
content: url('/test.svg');
}
I've written a Schematic that can be used by the library consumers to store the images inside a subdirectory of the assets folder of the application (e.g. src/assets/test-path). The Schematic does work as expected.
It does work when I add the following style inside the client's scss:
#import "test-company/test-lib/theme";
.a-client-test::before {
// This is just an example and assumes that the test image is located at this path.
background-image: url('../../assets/test-path/test.svg');
}
But as soon as I remove the line above (that actually uses the image from the assets folder and is not required at all). The path won't work anymore.
I've tested the following paths inside the library: ./test.svg, ~/test.svg, /test.svg. Only the latter does work but only with additional styles like the one above (that wouldn't be used) on app side. That's something I want to avoid as maybe we provide 50 icons on the library-side and it would be tedious to add these classes only to use the assets.
Some additional information:
I've added node_modules to the predecessor options in angular.json.
All other styles are working correctly. Only the image doesn't work.
I know that I can use ccsUrl: "inline" option inside the ng-package.json. However, I think this option only works (as far as I know) on styles that are used by components. But I actually copy the theme styles over after the build process. Additionally, the number of icons that are used inline shouldn't be too big, otherwise, the bundle size will increase and is therefore not an option for me.
I also don't know what is best practice for a scenario like that. I just couldn't figure out a proper way so far. But I assume writing a Schematic that copies over files is also not the best approach. Maybe there is a better way (e.g. a way to reference assets from the library but keep in mind I have the styles inside my library and the path is, therefore, complicated to figure out for all modules).
Just to make it clear again: My library has a scss file that uses an image. That image path is clear at the built time but doesn't work when used by an app. I can copy over the images, but that only helps when those images are used by the app somewhere in the styles. Then the path /image.svg works. The image as well as the scss that makes use of it are provided by my application.
Thanks for your help!

How to check CSS loaded size in Angular Application

Hope you all doing great.
I am using SCSS and Bootstrap in my Angular Application and as we know once Angular app runs, it converts these SCSS files to CSS version of it.
How can I check CSS file size generated as a whole for application as I need to show some reports for optimization tasks.
Any idea. I tried googling and here on Stack Overflow but couldn't find required solution. I can't even see any CSS file in Network tabs of Browsers.
Any Suggestion?
Assuming you are using Angular CLI for your project, which uses webpack internally...
Once you build a project. A dist directory is generated in the project root. Take a look into it and you'll find all the .js and .css bundles it might have generated.
Note - The size will vary based on what kind of build you do. For a production build, the sizes are going to be minimal, for other kinds of builds, if any, the sizes may differ.
You should go first in the Networks tab then reload the page. Once you reload it, click on CSS filter then you would see all the list of CSS included in your app, with the file size.
I didnt find any css generated in Network like above answer but I did a trick.
I went to webpack folder and there I found one generated CSS. ( Searched through a random CSS Selecto ).
I right clicked and saved it on desktop. If you check the properties of this CSS file, it shows the size in KB.

What is the best way to implement a theme / template in meteor or angular-meteor

I've been having trouble implementing templates bought in themeforest in a meteor app.
I'm wondering, what would the best way to implement a template into a meteor app.
Two ways that I think of right now are:
(Tedious way)
Place javascript in Compatibility folder and try to name them in specific alphabetic order in order to get them to work properly.
Place css in client/lib folder and try to name them in specific alphabetic order in order to get them to work properly.
Place fonts and images in the public folder.
The second way (I haven't tested it yet) is to place the template files in the public folder and just link them manually (the old/non-meteor way) in the index.html file.
Now I'm not sure if these are the correct ways to do this and I would like some information regarding this issue.
Thanks!
I've done this myself with a themeforest theme.
Put the theme's css file under /client - it doesn't need to be in /public
Use the class names your theme uses in your templates. Typically a theme will have 3x what you really need so this ends up being much less work than it might seem. If your theme is built on bootstrap then it's even easier.
My theme used fontello a lot for icons, I had to recreate the folder hierarchy under client/fonts and then make sure the cross-references were correct.
Typically themeforest themes don't use js that much, I completely ignored all the js that came with my theme and created what I really needed in Meteor.

Do I have to use Compass to modify CSS with Django-Grappelli?

I recently setup django-grappelli on my first django app. While I like the way it looks I want to customize the colors, and other CSS.
From my research, it looks like I will have to use Compass but I've never used Compass before and want to double check that this is the best method before I embark on that path!
Is Django-grapelli even the right choice for some one that wants to customize the color theme?
Things I tried
Modify the CSS in the Grappelli stylesheets but they are formatted in a way that makes it tedious.
Extend the style sheet but I am not sure where to do this for the admin.
Create a custom.css but could not figure out where to put the path
Thanks for your advice!
It seems to me like Compass is just a tool to write CSS. I've never used it, but at the moment I don't see how it could make modding the admin interface any easier than doing it manually!
Whenever I make changes to the admin (I've made changes to Grappelli, like you're trying to do), I always use what you've listed as number 2. I've never had any troubles! I can try to help you out, if you'd like to try again.
What I do first is go to my Python install directory and copy the Grappelli source from Lib/site-packages. I put this code in my project directory as a project-level app. So, if you're using Django 1.4, you'll have a folder that has your project folder as well as manage.py in it. Put the code there.
Then, using your favorite web developer tools (I prefer Chrome's), figure out which stylesheet you need to modify and which css file it's in. I do this by right-clicking the element and selecting Inspect Element. This brings up the dev tools, and at the right it tells you the css file its referenced from as well as which line its on. If you open up that css file in your favorite text editor and make changes to it, it should work!
Let me know if you're having any trouble with this. I can try to help you out further.
(and, P.S., I wasn't trying to be pedantic with a basic overview of the use of Chrome's developer tools. I was just trying to be helpful by not assuming anything. I hope you don't take it as an insult.)

Flex - how to switch to another SWC theme at run time?

My goal is to have more themes for my application and if possible, bundle them with the application itself, not load them at runtime using IStyleManager.loadStyleDeclarations().
Using the theme command-line option, you can have more than one "compile-time theme" bundled with your application according to docs:
theme filename [...] Specifies a list of theme files to use with this application. Theme files can be SWC files with CSS files inside them or CSS files.
However, I wasn't able to find an example how to actually do that (use the += syntax on command line?) and switch between those themes at runtime. What API should I use?
Using the theme command-line option, you can have more than one
"compile-time theme" bundled with your application according to docs:
Yes, You can add additional themes using the += in your command line.
I do exactly this for the Flextras mobile demos; including both the generic Spark theme with the Mobile theme to create the app.
However, both themes will be attempted to be used. I believe the second takes precedence. That means for every class where you want to use the "other theme" you have to specify that theme be used manually. This could get pretty complex very quickly; and you'll have to re-create a lot of spark skins in your application. I've done some work for a client around this who wanted to use our mobile DropDownList in both their normal application and in a mobile application from the same code base. I think the appropriate skin is conditionally applied at runtime using CSS; however we had to create a skin for the "non-mobile use" that explicitly specified the non-mobile skins for the individual elements (Such as the scroll bars)
