Communication problems with very large icon set

[polilluminato]

Hi everyone I'm trying to create a custom font with Flutter with 1600+ icon.

I already uploaded all the SVG on the fluttericon.com website and I managed to download the config.json but when I tap on Download it gave me a communication error

.

So I removed all the icons, reupload config.json, retried download but I got the same error.

I also tried to use fontello-cli like I found in the readme but with command

fontello-cli --config config.json --host https://fluttericon.com install

It gave me

/usr/lib/node_modules/fontello-cli/lib/fontello.js:39
        throw error;
        ^

How can I solve this issue and create my custom font?

[polilluminato]

I managed to solve my own issue by breaking all the icons in 7 chunks, generate 7 different .ttf and merge by hand all the 7 classes that fluttericon.com creates by exposing only one super class that merges all the stuff.

For now my problem is fixed but I leave the issue open to get other hints from the maintainer, or from you guys, on how to manage all in a better way.

[Flucadetena]

Today I had the same issue with only 24 icons. I manage to solve the problem by reducing to 20 icons, and after downloading once adding the other 4 and downloading again.

Don't really know what was happening ;)

[maerlynflagg]

i have the same issue today. i have 516, which are needed. it is a bad way to split and merge manually.

so same issue with website and same issue with the fontello-cli.

Workaround

upload all .svg to http://fontello.com/ or https://icomoon.io/ and download the font. then you can add the font zu flutter project. you have create manuelly the dart class. this is on many icons not really funny.

Please fix the issue. Or is it possible to generate the dart file locallly?

Edit I tried with 20 Icons, it worked but is not a nice solution to make 25 single packages and merge them manuelly together. there can be always come new icons to the set, so every time merging.

Hi guys. This is only happening with custom SVG, correct?

[Flucadetena]

Hi @ilikerobots I guess so. If you mean Only using custom svg's, no. By this I mean trying to download a file with custom and icons from some sources of the app.

But if you mean if it happens when only using icons already on the platform, I don't know.

It only happend to me when using custom yes.

If you need us to do some test or something, or even if we can help please let me know. Happy to help with this great tool.

[ilikerobots]

I've updated the site config to allow significantly larger HTTP request bodies (new limit 24m). I was able to download 1500+ custom icons with this config. Can someone listening on this issue also confirm?

Thanks for reporting and helping!

[Flucadetena]

Thabyou @ilikerobots this is a great tool. Essential now in my workflow. I don't have such a large set, but I'll do some testing and get back to you.

[maerlynflagg]

now the uploading and the download is working. i got my new TTF and my new DART file. but now, i have issues with the new icon dart file.

all old icon dart files and TTF files working fine. please look here #54.

[ilikerobots]

Thanks, closing.
