Flutter app on iOS causing phone to restart, no idea where to start
Hey guys, I expect this to get buried but man am I having a tough time with a rather random issue.I have a section of an app that is causing users' iPhones (ios13) to restart. I've pulled device logs, and the restart was unrelated to my app specifically, but did have information about the restart:Incident Identifier: EFF29247-7B41-4225-9DA7-1A6584CC5898CrashReporter Key:   6bb3f35ef170b67fd0897ab58b6394977d126decDate: 2019-11-18 11:17:20.66 -0600Reset count: 1Boot failure count: 0Boot faults:Boot stage: 0Boot app: 1610934444..."reason" : "Power assertion timeout for \"RTLocationAwarenessManager\".  Simply releasing it now.\nBacktrace for power assertion: pid 31 (0x1a1781fa4 0x1c419a80c 0x1c42a3058 0x1c42a32b8 0x19f25e610 0x19f25f184 0x19f20b404 0x19f20be28 0x19f215314 0x19f2aef88 0x19f2b1ad4)",This was the only remotely helpful piece that was tied to the crashReporterKey from the restart log entry. No location stuff is not running in the app at this stage, so RTLocationAwarenessManager seems entirely unhelpful.I've only been able to reproduce this a couple of times on an iPhone SE (iOS13), but it definitely seemed like going to this screen and staying there for a bit was the cause. However, for the users who regularly see this, it happens much quicker, and is consistently happening on that one screen of my app. I have rigorously run this through xcodes profiler and have a "low" energy rating, no weird network/cpu/ui loops, no memory leaks... nothing like that.Unfortunately, I come from mostly a native Android background (this issue is not happening at all on Android), so I'm at a loss really when it comes to obscure iOS related issues.Has anyone seen anything like this and could give me some sort of idea on where to start?

How to get movies genre from tmdb API
When i send a request and i get the results back i get something like this"results": [ { "id": 423204, "video": false, "vote_count": 578, "vote_average": 5.8, "title": "Angel Has Fallen", "release_date": "2019-08-21", "original_language": "en", "original_title": "Angel Has Fallen", "genre_ids": [ 28 32 ], "backdrop_path": "/k2WyDw2NTUIWnuEs5gT7wgrCQg6.jpg", "adult": false, "overview": "After the events in the previous film, Secret Service agent Mike Banning finds himself framed for an assassination attempt on the President. Pursued by his own agency and the FBI, Banning races to clear his name and uncover the real terrorist threat which has set its sights on Air Force One.", "poster_path": "/fapXd3v9qTcNBTm39ZC4KUVQDNf.jpg", "popularity": 169.408, "media_type": "movie" },......So it's easy to get the title and overview or other values that i can access them here but for example I've genre_ids that give me a number so i can use it directly as a genre for movies I've to send another request to get the genres ids and genre And i get something like this :{ "genres": [ { "id": 28, "name": "Action" }, { "id": 12, "name": "Adventure" }, { "id": 16, "name": "Animation" }, { "id": 35, "name": "Comedy" }, { "id": 80, "name": "Crime" }, ......But i don't know how to get the genres here!? What's the idea to compare the genre_ids from the results i have to the id in this genres to get the genres name?

New audio player plugin
I've published a new Flutter plugin for audio playback, "audiofileplayer".pub and sourceWhile there's a lot of audio player packages already, I like to think I've combined the best features from them, and, more importantly, addressed some common shortcomings. This plugin:Can play from local data from the Flutter assets without copying to other folders; also can play from remote URLs, and raw byte data.Has correct memory management via a dispose() method. (some other plugins leak the audio data on every load)Please give it a whirl, and file any issues on the Github issue tracker.Edit: formatting

Sqlite good practice: should I keep a local list variable of a table so that I don't need to run query everytime I insert a new row?
I am not sure which method is a better practice. Let say I have a table containing a bunch of to-do items. When inserting new item, should I 1) Append to a local list, insert into the table, display the local list with a widget. Or 2) Insert into the table first, then query the table and map the result into a list, display this list with a widget.

Click to expand a SliverAppBar
I have been wondering how to approach this with no luck.What I would like to try to implement is the ability to click a SliverAppBar so that when the title (or flexible space) is tapped, it expands to cover the entire screen. I would also like it to collapse back down to its previous size when the title (or flexible space) is tapped again.I have been thinking that maybe creating a custom PreferredSizeWidget to occupy the bottom widget and changing its preferred size on tap could work, but I still have the issue of correctly determining how much size it should occupy when it is expanded.If anyone has any idea or samples of code to share, I would really appreciate it. Thanks!

How to import a dart file from a directory from a local file?
I am a student and very new to flutter/dart so I am incredibly sorry if I make mistakes along the way or just sound like a noob.I have an application I am currently working on and I have some classes I want to import.I want to make a simple console application, but to not copy and to always have the same updated classes how do I import the classes from a folder.I tried the following:made a folder called "WindowsApp"made another folder called "lib" (because for some reason it is the only I can run the main)made a file "main.dart"and had the following codeimport '<directory>\\foo.dart';void main(){print('test');}it says that the directory doesn't exist? In java I remember doing something similar and it worked, but I seem to not have same logic work here.The research I have done it is still foggy as to what to do because one answer is to use Source, an other provided what I wanted, but didn't show the code and the code that was shown introduced a new thing called library. Is there no simple way like java where you just put in the directory and that is it?Do i need a full blown project with a YAML and all if I wanted to use API's and such?
