Mobile developers should pay much attention to flutter in 2019, well, this Project is for Flutter learning from zero. Every commit is base on milestone which means it can run exactly. so if you are also interested in Flutter, you can download and review this easy code based on commits.

I will commit code continuously, but learning guide such as README cannot be promised.

My hobbies:

• when I name a class name or class file name, I prefer Pascal Case, you can call it Upper Camel Case, rather than Under Score Case.

Notes

Flutter	iOS
widget	object/view
widget build	object init/loadView
StatelessWidget build()	object init/loadView
State build() -> StatefulWidget createState()	(UIControl layoutSubviews)/(UIViewController viewWillLayoutSubviews)-> (UIViewController set（UIControl + UIControlEvents)）
StatelessWidget vs StatefulWidget	❌NSObject vs UIViewController or ✅NSObject/UIView vs UIControl/UIViewController
StatefulWidget vs State	UIViewController vs (UIControl+ UIControlEvents)
StatefulWidget.createState and State.initState vs State.setState	✅(UIViewController init UIControl 、UIControl set first UIControlEvents render vs UIControl set another UIControlEvents render) or ❌ object.alloc vs UIViewController.viewDidLoad
Column	CollectView/TableView/StackView
Column(children:[])	TableView.cell
List	Array
List.map((element) => Card()).toList()	Array.enumObject then addObject
final	list default is mutableArray, if it is marked as final, means cannot be assigned.(Is it right that every assigning means allocating new space, and final means avoiding allocating?)
ListView vs Container vs Expanded	TableView vs initWithFrame:style: vs (init + autolayout)
ListView vs builder	TableView vs dequeueReusableCellWithIdentifier:
ListView vs itemBuilder	TableView vs tableView:cellForRowAtIndexPath:
ListView vs itemCount	TableView vs tableView:numberOfRowsInSection:

this.startingProduct vs widget.startingProduct
