Any ideas on how to approach a coloring book type app?
I hope this fits under a discussion and not a support forum, if the mods don't think so I apologize. I download some coloring apps for my kids and these apps are terrible! They are almost predatory in their in app purchases and ads for small children so I thought I should build my own for my kids. My background is in native app development but I have been switching over to flutter in my last 6 - 9 months and would love to build something that is actually fun for kids to use that is cross platform. I have been searching for some way to approach this but I haven't really come up with any good solutions on how implement a coloring book functionality. Anyway has anyone see any widgets that would work out for something like this: https://play.google.com/store/apps/details?id=com.fungamesforfree.colorfy&hl=en_US or this https://play.google.com/store/apps/details?id=com.pixel.art.coloring.color.number&hl=en_US (these are not my apps just used for demo purposes)

Logic for using pagination in listview
So I am currently developing a flutter app that uses a Django Rest Framework backend. So far everything has been great but I am confused about implementing pagination in my listview builder. This is the typical response I get from my api:

HTTP 200 OK { "count": 1023 "next": "https://api.example.org/accounts/?page=5", "previous": "https://api.example.org/accounts/?page=3", "results": [ … ] } 

I get a count that gives me the number of objects, the next page url and the previous page url. The next is null if we are on the last page and previous is null if we are on the first page.I already have the scroll controller for listview figured out so I don't need help with that.I just want to get your thoughts on my logic and see if there is a better way to implement this.I have basically decided to store the current index, previous index, and the next index in the provider and use them to update the url that gets requested to the API.Every time there is a get request to the API, we check and see if next is null in the response body and if it isn't we set the next index in the provider as current index+1.If next is null in the response body then we set next index to null and we don't try to request any more pages.If the next index is not null then when we are reaching towards the end of our current list we set prev index to current index, current index to next index, and the value of next index to null temporarily. We make a get request to the url and add the results to our list. The value of next index is updated if the response shows that we have more pages.If the listview is refreshed then we set prev to null, current to 1, and next to null. We completely clear the list and assign the new results.

Blog or tutorial for layering different widgets and keeping some layers transparent
What i am trying to achieve is i have a alphabet 'A' on the screen. Inside the text body i want to show a container whose height is varying. So in the background screen lets say the color is green. The text 'A' on the screen is transparent. Inside 'A' text is filled with color yellow. But the color lowers its height level gradually. And a new color is revealed for the reduced height space, lets say pink.

Handling transparent status- and navigation bars
Hello Flutter developers,Have any of you guys had any experience with changing the system status- and navigation bars to transparent, to allow your apps content to take up as much screen estate as possible?It is fairly easy to simply import SystemChrome and SystemUiOverlayStyle from the services.dart file, and then using that to set the bars to transparent. However with this method I found some problems with the systems icons as they would have to change their brightness according to the brightness of the app, which can both be changed from within the app with a toggle or a button, but also system wide from the system toggle of dark mode (which utilises the darkTheme parameter of the MaterialApp). This doesn't seem to be a problem if you don't have a transparent status- and navigation bar, seeing as the icons always have a background then.What I did to solve this was to create a stateful class that implements the WidgetsBindingObserver and then using that class to set the icon brightness according to the brightness of the app, whether the brightness is controlled by a button in the app itself, or if it has been triggered from the system toggle (which is the main reason for this class, as I haven't found any other ways to react to brightness changes from the system toggle).I'm wondering if having an observer at the top of the widget tree listening to phone changes to change the system icon brightness is a bad practice or not? What have you guys done to solve this issue? I'll happily share the class I've made with you if you want to see it.

Will Flutter Europe conference talks be available to public?
Flutter Europe is going to be held on 23-24 January and the tickets are all sold out a while ago. It looks like it became a big success even before staring. Congratulations to the community. Me wanting to attend so badly and not being able to anymore, I was wondering if after the conference the committee would be kind enough to share the videos with our community. If yes, I would not be so sad anymore:)Looking at the program of the coference I see there are some great subjects which all of us would benefit from. Since flutter is fairly new I believe this would be a very kind gift for our community. Thanks for considering.

If Firebase don't release suitable SDK's for desktop then it looks like the only route for the Desktop app is Flutter Web + Electron. Which isn't an optimal solution.
