SwiftUI’s GroupBox, OutlineGroup, and DisclosureGroup in iOS 14
SwiftUI groups were introduced with iOS 13. They act as containers for wrapping different view types and also let you work around the 10 ChilidItem limit of VStack and HStack.
SwiftUI, in its second iteration at WWDC 2020, offers us a few new group controls. Namely, GroupBox, DisclosureGroup and OutlineGroup are now available in iOS 14 and above.
Let’s walk through each of these.
GroupBox
GroupBox is a stylized container view with an optional Label, and earlier it was only available in macOS. Now you can use it to logically group views and build things like a login screen, a custom alert dialog, and more.
Here’s the code that shows how to create a GroupBox in SwiftUI:
GroupBox(label: Label("Enter Details"), content: {
VStack{
TextField("Username", text: $text)
Button(action: {}) {Text("Submit")}
}
})
View modifiers work the same on GroupBox as they do on any other view. For instance, you can set shadows. The below screengrab shows a neumorphic design of the GroupBox in SwiftUI:
Neumorphism is all about setting lights and shadows to give an extruding look, and that’s what’s done in the above code by using powerful view modifiers. The code is available in this gist.

report for multiple lcov.info files (-m, --multi)
It support to run for multiple lcov.info files with the followings directory structures:
1. No root module
<root>/<module_a>
<root>/<module_a>/coverage/lcov.info
<root>/<module_a>/lib/src
<root>/<module_b>
<root>/<module_b>/coverage/lcov.info
<root>/<module_b>/lib/src
...
2. With root module
<root>/coverage/lcov.info
<root>/lib/src
<root>/<module_a>
<root>/<module_a>/coverage/lcov.info
<root>/<module_a>/lib/src
<root>/<module_b>
<root>/<module_b>/coverage/lcov.info
<root>/<module_b>/lib/src
...
You must run test_cov_console on <root> dir, and the report would be grouped by module, here is
the sample output for directory structure 'with root module':
flutter pub run test_cov_console --file=coverage/lcov.info --exclude=_constants,_mock --multi

Use this package as an executable
Install it
You can install the package from the command line:
dart pub global activate test_cov_consoleUse it
The package has the following executables:
$ test_cov_console
Use this package as a library
Depend on it
Run this command:
With Dart:
$ dart pub add test_cov_consoleWith Flutter:
$ flutter pub add test_cov_consoleThis will add a line like this to your package's pubspec.yaml (and run an implicit dart pub get):
dependencies:
test_cov_console: ^0.2.2Alternatively, your editor might support dart pub get or flutter pub get. Check the docs for your editor to learn more.
Import it
Now in your Dart code, you can use:
import 'package:test_cov_console/test_cov_console.dart';example/lib/main.dart
import 'package:flutter/material.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {

theme: ThemeData(
// This is the theme of your application.
//
// Try running your application with "flutter run". You'll see the
// application has a blue toolbar. Then, without quitting the app, try
// changing the primarySwatch below to Colors.green and then invoke
// "hot reload" (press "r" in the console where you ran "flutter run",
// or simply save your changes to "hot reload" in a Flutter IDE).
// Notice that the counter didn't reset back to zero; the application
// is not restarted.
primarySwatch: Colors.blue,
// This makes the visual density adapt to the platform that you run
// the app on. For desktop platforms, the controls will be smaller and
// closer together (more dense) than on mobile platforms.

);
}
}

// that it has a State object (defined below) that contains fields that affect
// how it looks.
// This class is the configuration for the state. It holds the values (in this

// in the middle of the parent.
child: Column(
// Column is also a layout widget. It takes a list of children and
// arranges them vertically. By default, it sizes itself to fit its
// children horizontally, and tries to be as tall as its parent.

// "Toggle Debug Paint" action from the Flutter Inspector in Android
// Studio, or the "Toggle Debug Paint" command in Visual Studio Code)
// to see the wireframe for each widget.
//
// Column has various properties to control how it sizes itself and
// how it positions its children. Here we use mainAxisAlignment to
// center the children vertically; the main axis here is the vertical
// axis because Columns are vertical (the cross axis would be
// horizontal).

SwiftUI, in its second iteration at WWDC 2020, offers us a few new group controls. Namely, GroupBox, DisclosureGroup and OutlineGroup are now available in iOS 14 and above.

Understanding Grids in SwiftUI for iOS 14
SwiftUI was announced at WWDC 2019 and it paved a way for declarative programming for building interfaces. SwiftUI Grid comes in two different flavours, which includes LazyVGrid and LazyHGrid. As the name suggest, LazyVGrid is a Grid that flows in vertical direction and the LazyHGrid flows in horizontal direction.
If you are interested in videos then check out the following videos associated with this post.
Each Grid consists of GridItem, which dictates the structure of the cell displayed in the grid. GridItem can be fixed, flexible or adaptive. Let’s start with the fixed size GridItems.
Fixed GridItems
var columns: [GridItem] = [
GridItem(.fixed(100)),
GridItem(.fixed(100)),
GridItem(.fixed(100))
]
In the above code, we have created 3 fixed size columns of size 100. Now, we an easily use the LazyVGrid to create the columns and display information in the GridItem. This is shown below:
NavigationView {
LazyVGrid(columns: columns) {
Rectangle()
.fill(Color.red)
.aspectRatio(contentMode: .fit)
Rectangle()
.fill(Color.red)
Rectangle()
.fill(Color.red)
}
.navigationTitle("LazyVGrid")
}
As you can see that for the content of LazyVGrid, we have used Rectangle but you can use any View you desire.
You can add more Rectangles to the LazyVGrid by running a ForEach. A ForEach loop will return a type View with each iteration. The implementation is shown below:
NavigationView {
ScrollView {
LazyVGrid(columns: columns) {
ForEach(1..<20) { _ in
Rectangle()
.fill(Color.red)
.aspectRatio(contentMode: .fit)
}
}}
.navigationTitle("LazyVGrid")
}
