Trying to reach design from screenshot.
All elements in circle must be able to work with logic which include change color.
Gray and green'ish one elements are disabled and blue'ish is active.
Probably I should use some kind of canvas to get this done, but I am not sure.
Thanks for all response!
Edit:
Very important part of logic. I want to dynamicaly change number of those circular elements.
You would need to use custom painter to achieve this.
You can check out Flutter shape maker! its a tool that can help with drawing this out.

I am trying to create a level graph as given in image which changes on level up or down. I not sure what is the right way to achieve this.
Please help. Thanks in advance!
A combination of Stack and CustomPaint might do the trick, check boxes can be Containers in-front of separate CustomPaint so you can change the color of each one depending on the user level.
Actually i am trying to make the following UI but i am not able to achieve that sort of hole or transparent layer below the yellow button. Have tried glassmorphism plugin and backgrop filters to acheive the glass frost efftet. Just would like to know how to make that hole.
Desired UI:-
You can use clipRRect or clipRect to make this design. these two widgets will help you cut/clip the container in the required shape.
For more information, you can have reference from here.
I'm generating multiple widgets(Containers in this case) using a ListView.builder and I also use a custom ClipPath to give a custom shape to them.
I was wondering if would it be possible to translate or somehow overlay those list items in order to place them so that the background(black area in the attached screenshot) would be covered. By that I mean I want to place them right under each other, like puzzle pieces. To be able to fit them right under each other would probably mean they would have to be overlayed somehow. Was googling but without any success.
Hopefully there's some Flutter experts out there who are nice enough to guide me. Thanks a lot!
I have a CPTTradingRangePlot with a CPTTradingRangePlotStyleCandleStick style.
I'm looking for a way to highlight a specific (or a few) candlesticks with a different fill color (or a glow, or something), but I can't find a way to access individual candlesticks in a similar way that a CPTBarPlot has with -(CPTFill *)barFillForBarPlot:(CPTBarPlot *)barPlot recordIndex:(NSUInteger)index;
Am I missing something here?
Can I somehow maybe access a specific candlestick after the data load, and then change the fill color?
I was also thinking about adding an Annotation Layer, and maybe draw a circle around the specific candlestick(s), but I don't want to use an image, since it will get stretched and pixelated when I'll adjust it's size.
Is there any way to draw a vector-based shape as an annotation around the candlesticks?
Thanks for any help!
You can put a request for that feature on the Core Plot issue tracker. In the meantime, you can achieve the same look by using more than one plot, one for each different style.
I want to color the country on selection of the country from a tableView. Can you help me please?
Considering your case, let me give you a heads up that this would require edge detection (so if you haven't done that before, it will take a LONG time), though not lots of it and the following is just one way of approaching this problem:
1) Take out an image context from the map you have.
2) Apply relevant edge detection algorithms in the area you want and use a bright color to differentiate. Note that this way, the inside would not be colored and I can't tell you for sure if that's possible or not.
3) Add that context as a subView on top of the map.
Also take a look at the Quartz 2D programming guide for more tips.
I would suggest something different, though. Keep pre-stored images for all the possibilities and just put a UIImageView with that as its image in front of the map - this will save you a lot of headache.
