Grabbing JSON from the assets folder
Hi I'm not sure if a post like this is allowed but I haven't been able to find the answer anywhere else on the internet and I think this question is broad enough to help a lot of people. I'm currently using the googleapis package. Currently my private key is pasted straight into my code with r'''''' surrounding the key like they've put the private key in the example in the documentation. I don't like how I currently have my key copy pasted straight into my code and would rather keep a json file in my assets folder and pull the key from there. Is there a clean solution similar to how the open() method in Python allows you to open the file and then load the json as if it were just copy pasted into the code?

[MobX] Confused about different approaches
Greetings everyone,​since my application has reached a point in which vanilla setState handling is getting out of hand and loses a lot of readability and understanding, I'm about to rewrite these logical parts with one of those best practice solutions. After some researching i actually kind of liked the workflow of MobX. The fact that most boilerplate code gets generated by command and I just need to insert the Observer widget right where data gets displayed makes it easy to implement and increases the readability.​To get to the topic: as of right now I'm testing the possibilities of MobX to better understand how I should implement this in my main application. Since now there are 2 behaviors (which actually lead to the same reason) where I'm not sure how to properly handle those. I'm using a Settings Store class for handling user properties through the application:

/* 

Application uses an instance of Settings */ class Settings = SettingsBase with _$Settings;/* Store class which represents data (observables which will trigger the Observer Widget as the value changes) and actions which handles changes to those observables */ abstract class SettingsBase implements Store { SettingsBase();@observable ThemeWrapper themeWrapper = ThemeWrapper( currentThemeType: ThemeType.dark, theme: getThemeData(ThemeType.dark));

 @observable List<String> enteredWares = []; 

​First the themeWrapper property. If I'm changing it inside a function with the @action annotation like this:

@action 

changeTheme(ThemeType themeType) { this.themeWrapper.currentThemeType = themeType; this.themeWrapper.theme = getThemeData(themeType);the appropriate Observer widget won't get rebuilded since the themeWrapper Object itself didn't change - only its properties did! So in order to make this work, I either have to transform the ThemeWrapper class to be a Store just like Settings:

class ThemeWrapper = ThemeWrapperBase with _$ThemeWrapper; 

abstract class ThemeWrapperBase implements Store { ThemeWrapperBase({this.currentThemeType, this.theme});@observable ThemeType currentThemeType; @observable ThemeData theme; }or instead i could actually just call: this.themeWrapper = this.themeWrapper; after changing the properties which will also work. The second approach doesn't feel like the way it should be done but decreases the amount of needed Store classes and additional boilerplate code.​Same thing happens when instead of a simple object a collection like List is being used

@observable 

List<String> enteredWares = [];

@action 

addWare(String ware) { this.enteredWares.add(ware); }calling addWare won't trigger the rebuild of the appropriate Observer widget since again the object enteredWares doesn't get changed - its property which contains the Strings does. Again calling this.enteredWares = this.enteredWares; would make the trick here but feels wrong. In this particular case in order to solve this problem in the way as mentioned before, I would have to write my own collection which has its entries as an observable and the add / remove function as actions. This can't be the way to go either.​So what am I missing here? Is the second approach by re-setting the variable expensive performance wise or even has other drawbacks I'm not even aware of? Or should i actually just go for it? Other ways to handle this scenario with MobX? I would appreciate any kind of help here! :)

Easy way to test Flutter app?
Hi Everyone!I am develop Flutter app with Firebase backend.I have auth, notification, and Firestore. I am use scoped_model for manage state. I want add test to app for check app is work on many device.I have no experience add test to app.What is most easy way to test? I have read https://flutter.dev/docs/testing but still look complicate.Firebase Robo Test look very easy but it no work for Flutter because:Robo tests use the Android API to perform actions on Android UI widgets directly. That helps the tests explore your UI automatically, but also means that they need to be able to extract an Android UI hierarchy for a screen in order to run tests on it.This correct?What is most easy for beginner?​Thanks!
