}
for static icon i used
icon: FaIcon(FontAwesomeIcons.gamepad),
How to load icon based on the json response
This is not supported by Font Awesome Flutter.
There is another package to help you with that: Icons Helper
However, if you try right now, you will see that Icons Helper refers to an adobe icon that does not exist anymore. It has been removed from the package in the master on Git but not yet on PubDev.
You could also just integrate icons_helper.dart in your project and maintain the map you need in your app.

We are building an extension that visualizes some data for workspace files in our view using a class derived from TreeDataProvider. We wonder if there is a way to use file icons contributed by the current File Icons Theme for our custom tree items. Base icon class has a field icon: ThemeIcon which supports product icons. Wonder if something similar exists for referring to file-type icons?
Thanks
Seems like using resourceUri and ThemeIcon.File is the way to do it:
this.iconPath = ThemeIcon.File;
this.resourceUri = Uri.parse('_.js');
I want to use flutter inbuilt icons as assets. So I want default location where all of flutter icons are located in flutter folder of flutter installation.
This would seem to imply that there's a fontFamily named 'MaterialIcons'. Not sure you can get it easily from any part of the Flutter distro, but https://material.io/resources/icons/ will show how to download or reference the font for your material designs.
static const IconData ac_unit_outlined = IconData(0xe005, fontFamily: 'MaterialIcons')
I don't think they are. If you look at the IconData class (https://api.flutter.dev/flutter/widgets/IconData-class.html). You will see that the description says 'A description of an icon fulfilled by a font glyph.'
Taking an example of one of the Icon values:
static const IconData list_alt = IconData(0xe81b, fontFamily: 'MaterialIcons');
I believe what that is telling us is that the Icon is being defined by the position 0xe81b in the Unicode font family called MaterialIcons
Not an answer to the original question, but likely tangentially helpful...
To visually identify & search/filter icons, both from the included MaterialIcons from Google and those created by the Community, check out:
https://materialdesignicons.com/
And to use them, the related pub.dev package for material_design_icons_flutter.
I was wondering how one could use his own icons in a Flutter-Mapbox plugins' marker?
There's no default marker icon (no provided icon - no marker),
and there's not enough documentation on how to use a custom image.
adding a symbol (marker) is as follows:
mapController.addSymbol(
SymbolOptions(
geometry:LatLng(0.0, 0.0), // location is 0.0 on purpose for this example
iconImage: "pin"
)
);
whereas the IconImage, a String, is the field which should contain the data about the icon (obviously), but the given example repository doesn't clarify the needed parameters (url, path etc.).
Providing a path to the assets doesn't work (unlike other widgets). In the example, they provide the IconImage field the value airport-15, and when running the app, it actually works, but I can't seem to find the resources' location (it's not in #drawables or my assets folder, or any other place in the project)
You have to create a custom style on using MapBox Studio.
Create a new dataset if not already exist
Create tileset
Create new style & select customize basic template
Create new layer, give it a name for example my_sym and add newly created datasource
Then click on type & change it to symbol
Now click on my_sym two times. (first one will close the option menu & second one will open a new menu with symbol properties
Click on icon tab & select new icon. You can also upload your own svg icon.
Click on publish
Click on share it will show you the urls.
Copy the type of url & set styleString property.

As of release 0.0.5 it will be possible to load custom icon images for your markers. The idea is to add the icon image to your assets folder (for example: assets/symbols/custom-icon.png). If you specify this image as an asset in your pubspec.yaml and set the iconImage in the SymbolOptions to this path it will be loaded automatically.
Regarding the airport-15, this is an icon provided by the Android implementation of the plugin. It is part of the Maki Icons used in Mapbox. Because these icons are part of the Android implementation you will not find as a Flutter asset or an Android resource of the example app.
I'm trying to customize the logo on the signIn page using the following:
AWSMobileClient.sharedInstance()
.showSignIn(navigationController: self.navigationController!,
signInUIOptions: SignInUIOptions(
canCancel: false,
logoImage: UIImage(named: "MyCustomLogo"),
backgroundColor: UIColor.black)) { (result,
err) in
//handle results and errors
}
However, the default logo still appears but the background does turn black. I have MyCustomLogo in the project but it just does not take. I'm fairly new to Apple development so I'm sure I'm missing something simple or maybe I'm not. I just need help please :)
I am able to add a custom logo to my Amplify Drop-In UI using the iOS SDK. You have to be sure to add your logo assets in the Assets.xcassets folder for your project to know where to look and override. Also, I presume you named your logo MyCustomLogo as you show in your code block above. You don't need to specify .png.
I have implemented Barcode Scanner for my Ionic project for both iOS and Android.
But when my Scanner starts, I want to add a button inside the view and add an event to it.
I am using phonegap-plugin-barcodescanner plugin
Please help me with how to append something inside the scanning view.
If you want to add stuff to the layout of your scanner, you need to write code in the plugin itself.
YOU CANNOT INTERACT DIRECTLY WITH THE SCANNER FROM THE JS.
In fact, the plugin you use uses cordova.exec in order to launch the scanner view by passing it arguments.
For Android, you just have to know Java and some XML.
For iOS, you have to know Objective-C / Swift.
For Android, you may have 4 files to modify :
plugin.xml : home of all you dependencies
Your_Activity.java : java file which permits to interact with the scanner view itself by calling buttons, textviews, layouts, etc...
Your_Main.java : java file which gets and returns parameters from the js file of your plugin
Your_Layout.xml : xml file in res/layout which is composed of xml attributes interpreted by java
Beside that, I found two good plug-ins for cordova/ionic apps from GitHub :
phonegap/phonegap-plugin-barcodescanner
tjwoon/csZBar
And there's the expensive one, Scandit, which resolves all of your problems for about 200$ per month, check the pricing for every solution they propose.
If you use their SDK, you may be able to interact with the scanner view from js files because of their work, but they're the only company I know to do that. (perhaps ManateeWorks...)
Under this part is what I've been doing since mid-July, in order to give you ideas.
I'm currently making an ANDROID scanner layout for my ionic app.
You can find my GitHub repository here, I forked it from tjwoon's csZBar and I added some stuff my ionic app needs.
I guarantee nothing, but I'm pretty sure I'll implement an iOS layout soon (at least I'll try), and unfortunately I don't really know android / iOS mobile programming.
Here's a screenshot of the layout
I made a "tab bar" composed of 3 image buttons, a "top bar" composed of text views & image buttons. The scanner is embedded between these two.
There are pop-ups for the app's features, which pause the scanner and respond to click events.
See the README and Java files (csZBar/android/) for more information.
Don't hesitate to ask questions and/or inspect my code.
Warning
1) It's currently on development so use it at your own risks (use branch master, not develop)
2) I only modified the android part, not the iOS!
3) It doesn't work for Windows phone...
After adding plugin, installngCordova with bower install ngCordova
Add link to ng-cordova.js JS file above reference to cordova.js:
index.html
<script src="lib/ngCordova/dist/ng-cordova.js"></script>
<script src="cordova.js"></script>
Also, don't forget to add ngCordova module:
app.js
angular.module('myApp', ['ngCordova'])
Now you're ready to use the plugin like this:
Controller:
var module = angular.module('starter.controllers', []);
module.controller('BarcodeCtrl', function($scope, $cordovaBarcodeScanner, $ionicPlatform) {
$ionicPlatform.ready(function(){
$scope.scan = function() {
$cordovaBarcodeScanner
.scan()
.then(function(barcodeData) {
alert(JSON.stringify(barcodeData));
}, function(error) {
alert(error);
});
};
});
});
View:
<button ng-click="scan()">Scan</button>
