Let’s talk about developing the mentioned flutter glassmorphism login UI in flutter app, but first if you are new and want a complete setup and want to build your first app instantly, then click here, now let’s jump into understanding step by step of achieving the mentioned beautiful login page design widget in flutter app.
Introduction
We will be covering each and every detail on how to make this glassmorphism login beautiful template. Let’s see what we have used in it.
Glassmorphism Package
We have used a glassmorphism package to get the glass container that we have used in our login page. To implement it, first import the package using the pubspec.yaml.
glassmorphism: ^3.0.0
Get the latest version and use it in the dependencies section, as shown in the image above, then run pug get to import the package in your app. Click here to check the latest version.
Login UI Steps Explanation
Background Image
Scaffold(
body: Container(
height: double.infinity,
width: double.infinity,
decoration: BoxDecoration(
image: DecorationImage(
fit: BoxFit.cover,
image: AssetImage('assets/development.jpg')))
)As you can see, we have used scaffold, and in its body constructor, we have used a container, inside that container’s box decoration, we have specified an image. First you have to make an asset folder in your app, then paste image there and then specify the location in pubspec.yaml like shown below:
Glassmorphism Container And Top Circular Image
Align(
alignment: Alignment.topCenter,
child: Container(
height: 80,
width: 80,
decoration: BoxDecoration(
shape: BoxShape.circle,
image: DecorationImage(
fit: BoxFit.cover,
image: AssetImage('assets/cartoon.jpg'))),
),
)By implementing this, we can see a circular image stacked on top of the glassmorphic container. We have used a container, then in its child constructor, we have used a stack widget. In its first child, we have use a glassmorphic container, in which we will define our email, password, forgot password, login clickable container and sign up clickable text. In the second child, we have used a container and by giving it an image, using its image decoration constructor of the box decoration class, we can see a circular image on top of our glass container. Click here to learn how to implement stack widget properly. Let’s see how the glassmorphic container is implemented:
GlassmorphicContainer( width: 350, height: 370, borderRadius: 20, blur: 5, alignment: Alignment.bottomCenter, border: 2, linearGradient: LinearGradient( begin: Alignment.topLeft, end: Alignment.bottomRight, colors: [ Color(0xFFffffff).withOpacity(0.01), Color(0xFFFFFFFF).withOpacity(0.05), ], ), borderGradient: LinearGradient( colors: [ Color(0xFFffffff).withOpacity(0), Color((0xFFFFFFFF)).withOpacity(0), ], ),)
We have used the glassmorphic container class:
- We have given the container a height and width using its height, width constructors.
- We have used the border radius constructor to make the edges of container rounded.
- We have used blur constructor to blur the background of container, high values means more blurred background.
- For gradients, we have used the linear gradient constructor, for giving gradients to border, use the border gradient constructor. In the linear gradient class, we have used the colors constructor and given it two colors of different values.
By implementing this, we can now see a glass effect container in our screen. Let’s see how it looks now:
Email and Password Textfield
TextField( style: TextStyle( color: Colors.white.withOpacity(.8), fontSize: 14), decoration: InputDecoration( enabledBorder: UnderlineInputBorder( borderSide: BorderSide(color: Colors.white70)), prefixIcon: Icon( Icons.email, color: Colors.white.withOpacity(.8), size: 20, ), prefixIconConstraints: BoxConstraints(minWidth: 35), hintText: 'Enter your email', hintStyle: TextStyle( color: Colors.white60, fontSize: 14)), ),
We have used a column widget, inside it we have used an email and password textfield. We have also used a forgot password text below password textfield.
Sign In Container And Sign Up Text
height: 45, width: 320, alignment: Alignment.center, decoration: BoxDecoration( borderRadius: BorderRadius.circular(60), border: Border.all(color: Colors.white70)), child: Text( 'Sign in', style: TextStyle( fontSize: 15, color: Colors.white.withOpacity(.8), fontWeight: FontWeight.w500), ), ))
