Welcome to another Flutter Widget of the Day post. Today we have Wrap widget. Look at the following screen shot

Behind the scene

 body: Center(

        child: Row(


          children: <Widget>[
           FlatButton(child: Text('Butto1'),),
           FlatButton(child: Text('Butto2'),),
           FlatButton(child: Text('Butto3'),),
           FlatButton(child: Text('Butto4'),),
           FlatButton(child: Text('Butto5'),),
           FlatButton(child: Text('Butto6'),),


          ],
        ),
      ),

As we know for arranging controls in horizontal manner we use Row widget and for vertical use Column widget.

The screen bump with a Yellow bar, which is caused by controls that is not fitted on the screen. Flutter has beautiful way of showing Errors, lol.

To solve the issue like this, Flutter has a special Widget called Wrap which wrap the contents to next line as we saw on the following screenshot

and the code will be as follows

body: Center(

        child: Wrap(spacing: 3,


          children: <Widget>[
           FlatButton(child: Text('Butto1'),),
           FlatButton(child: Text('Butto2'),),
           FlatButton(child: Text('Butto3'),),
           FlatButton(child: Text('Butto4'),),
           FlatButton(child: Text('Butto5'),),
           FlatButton(child: Text('Butto6'),),


          ],
        ),
      ),

Wrap has property children as Rows has ,so we can lay the controls as in Rows. It has many other property such as spacing which is handy . And the following quick video will help you further.

Welcome to another Flutter Widget of the Day post. Today we have AboutDialog widget, which can be must have for every app, since every developer tech like to have some license info for the users.

How to use the AboutDialog

It is a good idea to create function to show the dialog which return a AboutDialog in a Flutter Manner as follows.

 void showAboutDialog({
    @required BuildContext context,
    String applicationName,
    String applicationVersion,
    Widget applicationIcon,
    String applicationLegalese,
    List<Widget> children,
    bool useRootNavigator = true,
    RouteSettings routeSettings,
  }) {
    assert(context != null);
    assert(useRootNavigator != null);
    showDialog<void>(
      context: context,
      useRootNavigator: useRootNavigator,
      builder: (BuildContext context) {
        return AboutDialog(
          applicationName: applicationName,
          applicationVersion: applicationVersion,
          applicationIcon: applicationIcon,
          applicationLegalese: applicationLegalese,
          children: children,
        );
      },
      routeSettings: routeSettings,
    );
  }

Now we are ready for calling the function inside the floating Actions button. You can now add all relevant information about your app, name, icon, version, etc as follows

 floatingActionButton: FloatingActionButton(
        child: Icon(Icons.help),
        onPressed: () {
          showAboutDialog(
              context: context,
              applicationName: "My APP",
              applicationVersion: "Beta",
              children: [
                Text('Developer: Manoj A.P'),
                Text('can be reached @ manojap@outlook.com'),
                Text('Web:' + 'http://manojap.github.io')
              ],
              applicationIcon: Icon(Icons.games));
        },
      ),

Besides there is children : [ ] which is used to add additional information in case you need them as a list of Widgets of your choice.

You may already noticed that flutter automatically included package license info for you, it can also be done manually

SafeArea is must have widget for any app developing with Flutter and Dart. So what is SafeArea for ?

As the name indicates it secure the mostly you want to cover, it helps to prevent overlapping of UI to Notification area, bottom navigation and edges of the screen. So you can keep the app away from different type of notches, curved edges , and other hardware features.

All you have to do is to wrap your widgets with SafeArea() widget as follows

 SafeArea(
        child: Scaffold(
