New post on /r/flutterdev subreddit: Flutter for a map focused app? Hello everyone,I'm currently in the process of building a project that needs an app for iOS as well as Android. I already built the backend and the web app, the web app uses React. I initially thought about building both apps with react native, which is not really a feasible option due to the limited map support inside React Native. I then considered building native Apps for both platforms, but since I'm a solo developer on that project, that's really not an option. Since flutter is getting more and more mature and I saw the flutter engage contents, I thought I might check on flutter again. I have some limited experience with flutter and used it to built fairly simple blog style applications in the past.My current project is heavily focused on geo data and maps, so the map will be the core component of the mobile apps. I haven't decided on the map provider yet, but its a decision between Google Maps and Mapbox (as of now, I'd prefer Mapbox).For Google Maps this seems to be the official package by Google, this one seems to be the official Mapbox package. Mapbox already states that their package only exposes a small subset of API methods in its flutter SDK, how is it with Google Maps? How limited are the Packages in terms ofGesture supportDrawing on maps (especially (custom) markers, driving routes and poly lines)Performance (including caching etc)?Maybe someone already has experience building map heavy applications with flutter? Which mapping provider did you use? Did the official package suit your usecase or did you have to build additional functionality for the maps yourself?Maybe someone can share some of their own experiences March 15, 2021 at 10:06AM by mooo99 https://ift.tt/3bKg6Ka

New post on /r/flutterdev subreddit: How to work best practise with user specific data from firebase firestore Hello together,I'm currently diving deeper into NOSQL databases (I'm working with flutter) and I'm really a fan of the official firebase youtube series "Get to know Cloud Firestore" https://www.youtube.com/watch?v=o7d5Zeic63s&list=PLl-K7zZEsYLluG5MCVEzXAQ7ACZBCuZgZ&index=4Because of the many possabilitys im quite unsure to some topics which might look really easy for you guys but I kind a like break my head.Let's say we have the following scenario:there is a dating app where you can like people and there are scores and you can show up the favorites and you have kind a like a list where you can see random 10 profiles.So like alot poeple are saying "Demoralization in NOSQL" is a good approach to work with. Saving parts of data as a duplicate to ensure we don't have to do 2 queries while fetching alot of informations we never would use.For example lets say on the home screen there is a list of 10 men profiles and below that we have a likes count and the 3 recently liked people as small bubbles with their profile pictures. they would be fields from a users collection and it wouldn't be good to call an extra query for the users only to retrive profile image and name field rather than just saving those fields as duplicate with the profiles. as extra field. That seems fine to me.-----------------------------------------------But what happens if we want to show the clients a list of men profiles and see if they have already liked the profile by showing a filled heart or border heart? (Also imagine instagram with the hearts showing if liked or not) How would the approach look like for this and why ?does somebody have a best practise here? This is kinda like user specific data, how would I structure my data and how would the query look like?P.S: Also im not sure how many reads and writes each function takes and what about doc.exists() ?. Is there a way we can say like when we are running examplefuntion() which is retrieving something, that the console says oh hey that was 100 reads 0 writes?P.S: Because im quite a rookie and im watching a lot videos and the documentation im not sure when to use duplicate data and when to use cloud functions. Would be nice if someone could clear things up here.Im really thankful for everyone reading my post here and answering my questions! March 15, 2021 at 10:28AM by md186 https://ift.tt/3s0AU5K

New post on Flutter Dev Google group: Index in string and list There is some possibility that the way to do this is added: String lastTwo = value1 [value1.length-2] + value1 [value1.length-1]; like this: String lastTwo = value1 [-2] + value1 [-1]; It is much faster and easier.

New post on /r/flutterdev subreddit: DocxTpl flutter plugin. A word templating plugin in flutter I finished .docx template plugin that use jinja2-like tags in .docx doc to easily generate the doc in flutter from a word document template. A very basic approach for now, i have big plans and contributions and PRs are welcome 😁. I plan to add more complex tag but above all, to make it easy to flutter like widgets to create and generate document content (inspired by the pdf flutter plugin)https://pub.dev/packages/docxtpl# March 15, 2021 at 08:28AM by don9ld https://ift.tt/30IXJ22

New post on /r/flutterdev subreddit: How hard would it be to make a team journal/schedule app? I can't get into specifics but I had an incredibly negative experience with contractors (not Flutter related) - they bailed on a relatively simple app (a group of people sharing notes/schedule with notifications when a new one is added) because I guess one of them had a mental health breakdown and the other did not tell us (after 6 months passed by).I have the free time to learn Flutter and it seems SO POWERFUL. I'm 1/2 through the App Brewery course and I feel like after completing the course I'll have a firm grasp on how to use flutter.Maybe it's a silly question - but do you think after the course I'd have the capability to make a team journal app? I'm just a little demoralized after the negative contractor experience and am wondering if I have reason to be optimistic? March 15, 2021 at 05:57AM by DracoDude1 https://ift.tt/3qNMoIo

New post on /r/flutterdev subreddit: The responsive_styled_widget package now supports explicit animations Hello everyone.

New post on /r/flutterdev subreddit: Why can't firebase be written in pure dart? (the current uses platform channel codes and not compatible with all platforms) First of all, firebase uses WebSocket for real-time communication. And WS can be written with pure dart. So I'm wondering why do the current firebase plugins from the flutter team are written with platform codes. Can't it be done with pure dart alone? What part/s of firebase can't be written with pure dart?I kind of get it though for example with Notifications. Different platforms have different ways to show notification so platform codes are needed. But what about database or firestore, they just send and receive data that has nothing to do with the platform at all.Why is this a problem?Because currently, the firebase packages are way too scattered. The package for the web is separated, the package for mobile and macOS is also separate, and lastly, the current versions of these firebase packages don't support windows and linux yet.References:web_socket_channel - WS package on pub.dev written by people from google. compiles to native and javascript so the web is possible. And meaning it supports every platform listed on pub.dev (mobile, web, Linux, Mac and win).Work with WebSockets - an official guide from flutter.dev about working with WebSockets in flutter.Firebase Callbacks - what's the underlying trigger? - a stack overflow thread about firebase using WebSockets.firedart - an interesting firebase package that supports almost all platforms and pub.dev. But it doesn't show the web compatibility badge on it. March 15, 2021 at 01:38AM by yurabe https://ift.tt/38EgJDi
