7 Flutter Development Hacks

  1. Add Timer using Flutter App Development

If you want to execute a piece of code after some time in the Flutter app development process you have to use the Timer class. Timer class will specify the time which you want to delay the execution and after that time period code will be executed inside the Timer.

void periodic() {

Timer.periodic(

Duration(seconds: 1),

(Timer time) {

print(“time: ${time.tick}”);

if (time.tick == 5) {

time.cancel();

print(‘Timer Cancelled’);

}

},

);

}

  1. Show Item Independently From ListView Using Flutter App Development

ListView makes its child scroll. Most of the time, you need a separator to differentiate between every child of ListView. This separator is usually a divider, which can be a line.

ListView.separated(

itemCount: data.length,

separatorBuilder: (BuildContext context, int index) => Divider( height: 3, color: Colors.white),

itemBuilder: (BuildContext context, int index) {

return Container(

height: 150,

color: Colors.red,

child: Center(

child: Text(‘${data[index]}’),

),

);

}

)

  1. Dismiss Keyboard Using Flutter App Development

To dismiss Keyboard, you have to set focus on a different node as shown in the example below using the Gesture Detector.

GestureDetector(

onTap: () {

FocusScope.of(context).requestFocus(FocusNode());

},

child: Container(

color: Colors.white,

child: new Column(

mainAxisAlignment: MainAxisAlignment.center,

crossAxisAlignment: CrossAxisAlignment.center,

children: [

TextField( ),

Text(“Test”),

],

)

)

  1. Create a circle shape image using Flutter App Development

ClipOval widget clasps the child widget in a circle or oval shape. You can reshape the child
widget by altering width and height. If width and height are equivalent the shape will be circular. If the width and height are specified in a different way then the shape will be oval. Let’s put light on this with the help of an example:

ClipOval(

child: Image.network(

imgUrl,

fit: BoxFit.fill,

width: 190.0,

height: 190.0,

),

);

  1. Set the background image to your Container using Flutter

Do you need to set the background image to your Container? And you are utilizing a Stack to do so? There is a better way to do so. With the help of decoration you can set the image in the container.

Container(

width: double.maxFinite,

height: double.maxFinite,

decoration: BoxDecoration(

image: DecorationImage(

image: NetworkImage(‘https://bit.ly/2oqNqj9’),

),

),

child: Center(

child: Text(

‘Flutter.dev’,

style: TextStyle(color: Colors.red),

),

),

),
