In this article, we will be creating a beautiful signup flutter form UI design, we will be using flutter textfield widgets, flutter custom check box in flutter signup ui, flutter column widgets, flutter row widgets, flutter gradient color, flutter text widgets, flutter gradient containers and much more to make the UI looks more attractive.
The widgets that we will be using in this signup flutter form UI design are all discussed in detail in the previous articles, so if you want, then you can check them. If you want to complete setup on how to install flutter then click here. So without wasting any more time, let’s just get right into implementing our beautiful flutter signup form UI design.
Implementation
Let’s start implementing our design step by step, let’s start with background color.
Background Color
SafeArea( child: Scaffold( body: Container( height: double.infinity, width: double.infinity, decoration: BoxDecoration( gradient: LinearGradient( colors: [Colors.orange.shade200, Colors.orange.shade900])), ), ), )
We have used a container in the body constructor of flutter scaffold, using the gradient constructor of the box decoration class, we have given it a linear gradient or orange color with different shades. Let’s see how the background looks now:
Title Text
We will be using a title text named ‘Sign Me Up’, that will be placed above. Let’s check the code for implementing it:
Row( mainAxisAlignment: MainAxisAlignment.center, children: [ Text( 'Sign', style: TextStyle( fontSize: 30, fontWeight: FontWeight.bold, color: Colors.white, shadows: [ Shadow( color: Colors.black45, offset: Offset(1, 1), blurRadius: 5) ]), ), Text( ' Me', style: TextStyle( fontSize: 30, fontWeight: FontWeight.bold, color: Colors.orange.shade700, shadows: [ Shadow( color: Colors.black45, offset: Offset(1, 1), blurRadius: 5) ]), ), Text( ' Up', style: TextStyle( fontSize: 30, fontWeight: FontWeight.bold, color: Colors.white, shadows: [ Shadow( color: Colors.black45, offset: Offset(1, 1), blurRadius: 5) ]), ) ], )
As we can see, we have used a row widget and inside it, we have used three text widgets, the text sign comes in the first one, me in the second one and up in the last flutter text widget. We have also customized our text widget by giving it color, size, shadow etc. Let’s see how it looks:
Username And Email Textfields
Let’s now add flutter textfields, we will use username, email, password and confirm password textfield. Let’s see the code for implementing it:
TextField( style: TextStyle(color: Colors.white, fontSize: 14.5), decoration: InputDecoration( prefixIconConstraints: BoxConstraints(minWidth: 45), prefixIcon: Icon( Icons.person, color: Colors.white70, size: 22, ), border: InputBorder.none, hintText: 'Enter Username', hintStyle: TextStyle(color: Colors.white60, fontSize: 14.5), enabledBorder: OutlineInputBorder( borderRadius: BorderRadius.circular(100), borderSide: BorderSide(color: Colors.white38)), focusedBorder: OutlineInputBorder( borderRadius: BorderRadius.circular(100), borderSide: BorderSide(color: Colors.white70))), )
We have used a username textfield, we have given it a hint text, hint style, this is the text that we see be default, when we haven’t added our text in the text field. We have also used the enabled border and focused border constructor to decorate the borders of the text fields, we have made the border rounded and of white color. We also have used prefix icon which is the icon that is shown before the hint text or the text that we will add after clicking on the textfield.
The email textfield is also customized using the same properties, so we only have used the username textfield code above. Don’t worry, the whole screen’s source code will be provided in the end. Let’s see both the textfields now:
Password And Confirm Password Textfields
Password and confirm password textfields are also customized using the same properties which were used for username and email fields.
In addition, we have used the suffix property, by using it, we have specified a visibility icon that we can see in the end of both password and confirm password textfields. It is used to show whether the user wants to see the password while typing it or not. By clicking it, the password text will be visible, clicking it again will hide it again.
Of course, we have to implement a simple logic for this, which we have already implemented in our source code. The icon will also change depending on whether the password is shown or not. Let’s see our password and confirm password textfields:
Flutter Custom Check Box
We have created our own custom options to let the user select whether to select a male or a female option. Let’s see the code for its implementation:
Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: [
GestureDetector(
onTap: () {
setState(() {
maleSelected = true;
femaleSelected = false;
});
},
child: Row(
children: [
Container(
height: 20,
width: 20,
alignment: Alignment.center,
margin: EdgeInsets.only(right: 10),
decoration: BoxDecoration(
shape: BoxShape.circle,
border: Border.all(color: Colors.white60)),
child: maleSelected
? Container(
margin: EdgeInsets.all(4),
decoration: BoxDecoration(
shape: BoxShape.circle,
color: Colors.white70),
)
: SizedBox()),
Text('Male',
style: TextStyle(
color: Colors.white70, fontSize: 14.5))
],
),
),
GestureDetector(
onTap: () {
setState(() {
femaleSelected = true;
maleSelected = false;
});
},
child: Row(
children: [
Container(
height: 20,
width: 20,
alignment: Alignment.center,
margin: EdgeInsets.only(right: 10),
decoration: BoxDecoration(
shape: BoxShape.circle,
border: Border.all(color: Colors.white60)),
child: femaleSelected
? Container(
margin: EdgeInsets.all(4),
decoration: BoxDecoration(
shape: BoxShape.circle,
color: Colors.white70),
)
: SizedBox()),
Text('Female',
style: TextStyle(
color: Colors.white70, fontSize: 14.5))
],
),
)
],
)
We can see that we have used Boolean values for this, we have implemented some logic, so whenever one option is selected, the other gets unselected automatically.
Flutter Gradient Button Container
We have used a container and customized it, we have given it a gradient background color, a child text widget, a shadow and a circular border radius, we also have wrapped it inside a flutter gesture detector widget so its clickable now and we can perform actions by clicking it. Let’s check the code out:
GestureDetector(
onTap: () {},
child: Container(
height: 53,
width: double.infinity,
margin: EdgeInsets.symmetric(horizontal: 30),
alignment: Alignment.center,
decoration: BoxDecoration(
boxShadow: [
BoxShadow(
blurRadius: 4,
color: Colors.black12.withOpacity(.2),
offset: Offset(2, 2))
],
borderRadius: BorderRadius.circular(100),
gradient: LinearGradient(colors: [
Colors.orange.shade200,
Colors.orange.shade900
])),
child: Text('Signup',
style: TextStyle(
color: Colors.white.withOpacity(.8),
fontSize: 15,
fontWeight: FontWeight.bold)),
),
)
As we can see, this is the gradient container that works just like a button, means its clickable and we have done our customization to this container which you can see in the above code.
Flutter Login Container Button
We have customized our login button by using the properties that we have used for the signup button. But removing and adding some properties like removing the shadow and background color and adding the border color to it.
Congrats, we have successfully developed our registration form UI in flutter app, let’s now look at the complete source code.

That’s all for this article, hope you enjoyed it and have learnt a lot from it. Implement it in your code and share your experience with us. We would love to see how you have used it in your flutter app. We would be looking forward for your response. Hope to see you in our next articles in which we will dig deep into other amazing Flutter widgets. Thank you.
