A note to where you put your icon images when developing (using appicon.co generated images)

Android
/android/app/src/main/res
*replace the folder mipmap-hdpi, mipmap-mdpi, mipmap-xhdpi, mipmap-xxhdpi and, mipmap-xxxhdpi with the folders generated by appicon.co

iOS
/ios/Runner/Assets.xcassets
*replace the folder AppIcon.appiconset with the folder generated by appicon.co

Xcode and iOS compatible version

kenjmoj — Fri, 17 Apr 2020 03:42:01 +0000

A quick note to what version should your Xcode is, in order to run your app during development.

Xcode major version MUST be 2 behind, and minor has to be equal or ahead from your iOS version.

e.g.
Xcode version 11.2.1 and iOS version 13.2 --> Compatible!
Xcode version 10.1 and iOS version 13.1 --> Not compatible!
Xcode version 11.4 and iOS version 13.3 --> Not compatible!

To check your iOS version, go to Settings/General/About
and for your Xcode, either on the first screen (where it says Version), or at about Xcode window.

Using Git - Steps using with Visual Studio Code / Flutter

kenjmoj — Mon, 26 Aug 2019 15:28:00 +0000

Git is confusing. I am aware hot useful it is, but often I forget how to use it (especially if programming is not your day job). Hence I am documenting here how to use it ,especially when using with Visual Studio Code for Flutter.
I am a novice Git user, so I hope to update this page while learning how to fully use it.

Git Basics of the Basics

First, if you don't know what Git is in the first place, visit pages like this one - https://www.freecodecamp.org/news/learn-the-basics-of-git-in-under-10-minutes-da548267cc91/
and there are lots more available over else where.

Git Basics

Git Directories

Keep in mind that there are three directories in git.

Your Working Directory, essentially the folder where you are currently coding
The Index folder, this is where you stage your code
Finally the Head, this is where the code resides once you commit it

The Flow

Here is a basic flow when using git

Create a Repository
Make changes to your code
Stage code (this is when you move your current code to the Index)
Commit code (the code now is in the Head)
Push code (Finally, this pushes your code to the remote repository)

simple.

Detailed Steps using VSCode/Flutter

For new Projects

Create Flutter project
Go to Source Control
Click the plus sign (Initialize Repository)
Select the project folder you just created
Notice on the left pane, files are being put in to repository
Hover on Changes, then click the plus sign (Stage All Changes)
Click on the check sign (Commit)
Go to GitHub
Create a repository
Copy your repository URL
Go back to VSCode
Open the Command Palette
Execute Git: Add Remote
Specify a name (e.g. origin)
Enter your repository URL, then enter
Now push your code! Click the three dotted icon, select Push

Flutter/Dart - adding a value of a list to a list

that is,

...

Yep, that's it. That's the code. This is the spread operator.

Let's assume you have a list "List", and you want to take the value out of this list and add those value to the surrounding list. It will look something like this,

children: [
  ...List

]

above will take out the value inside the List and add it to the children:
