Use DroidText for barchart - itext

I am just trying different pdf making library for some research in android. I have one question regarding this. How can we make bar charts , pi charts using droidtext as PdfGraphics2D is not available. Not from itext, I already know.

You can use a chart library like achartengine (https://code.google.com/p/achartengine/) or afreechart (https://code.google.com/p/afreechart/) to create the chart and save it as an image. Afterwards add the image file to the pdf.
There are currently no plans to add PdfGraphics2D support to droidText.

How do I modify a library in flutter?

I'm using a library that draws barcodes and under them it drows the barcode number, however it draws text just in black color. I found the code that chooses the color during this operations, however when I try to change this code library from Colors.black to Colors.white and I save it, it doesn't save for some reason. So I suppose there is a different way to modify code from library, but I don't know how.
#Gabriel, You can easily copy .dart files from the package/library you're using to your project and modify the code to your liking. For e.g. if you are using https://pub.dev/packages/toggle_switch, then you can access the source code from the GitHub location of the package in pub.dev and download it from GitHub,
You can then copy .dart files from <project>/lib to your <project>/lib and modify them accordingly. Make sure you add reference in the source code to credit the original developers and add their GitHub link.
Good luck!

how to load text layer in mapbox-gl style / tileset

I'd like to do exactly what https://api.mapbox.com/styles/v1/zugaldia/cimteac7b00mrb8m7okkkol8d.html?title=true&access_token=pk.eyJ1IjoienVnYWxkaWEiLCJhIjoiY2ltNnI0YXM0MDA0YXR5bHgxOTU0N2h5YyJ9.kBUkyDqT5S1gJOsMIAdJSw#11/38.8993/-77.0146 is doing.
It seems to use the MapBox GL tileset and style to place text on the map. It even shows more text at a zoomed in level.
How do we do that?
Can you point to a detailed example or video that shows the steps for loading the tileset (maybe from a GeoJSON file, etc)
Thanks.
It is really nice that we can do so much without javascript at all :)
This makes it easier for Android and iOS etc.
Notice the text for the School names:
Then when you zoom in, you see the text for the crime:
That is indeed a very nice map, he created it using Mapbox Studio uploading crime and school data as layer sources. You can learn more about creating your own map style by following along with the "design a map" guides. Once you've created a map you'll need to get the style ID by doing this:
(source: mapbox.com)
and then...
(source: mapbox.com)
Now you also mentioned using these maps within your Android or iOS app which is similar to using the api (link you gave above). Follow this example about including Mapbox studio style in your Android app. The example places the style url within XML like so:
<com.mapbox.mapboxsdk.maps.MapView
...
mapbox:style_url="mapbox://styles/<your-account-name>/<your-style-ID>"
/>
Hope this helps!
