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?

DropdownButtonFormField not showing inside Row
Hi, new to Flutter here and im adding a DropdownFormField and TextFormField side by side inside a Row. This is how it looks like

Widget build(BuildContext context) { return Form( key: _formKey, child: SingleChildScrollView( child: Column( children: <Widget>[ Row( mainAxisAlignment: MainAxisAlignment.start, children: <Widget>[ DropdownButton( hint: new Text('Select Gender'), items: _salutations, value: client.salutation, ), SizedBox(width: 20), new Expanded( child: TextFormField( decoration: InputDecoration(labelText: 'Name'), validator: (value) { return value.isEmpty ? 'Empty name.' : ''; }, ), ), ] ) ], ) ), ); } 

That code currently shows because it is DropdownButton. But if I change it to DropdownButtonFormField it won't show, as long as it is in the Row(). Why is this?I wish to use DropdownButtonFormField so that the height of the Dropdown will be the same as the TextFormField since the current code shows the dropdown with a smaller height.
