Flutter Border is an outline widget that covers the entire container on all four sides: top, right, bottom, left. Flutter uses borders to identify one component's coverage area. We can customize the border by using its border property.
In Flutter, we can define the border of widgets inside the scaffold. Therefore before adding a border of a widget we need to define a Scaffold. When we creating a sample flutter app, it comes with the default scaffold.
So, are you ready to make use of this widget package in the Flutter application? If so, then let's quickly jump into the usage and the ways a border can be modified and used to make user-friendly apps. Here I am going to use an open-source UI Library known as GetWidget to build this border widget in Flutter.
Border Widget for Flutter
It allows you to speed up your Flutter app development by 20-30%. It has almost all widget that allows you to enhance your Flutter UI design and speed up flutter development with fully customizable features.
Now here is i am going to talk about what is GetWidget Border widget and how we implement this on Flutter app to build awesome Flutter Border widget for an app.
How to Get Started
Now here is the guide about how we should start developing the GFBorder Widget with the use of the GetWidget UI Library.
First, Let go with Getting started, It will guide you on how to start building a beautiful Flutter template with the GetWidget UI library. Now, we have to install the GetWidget package from the pub.dev and use our 1000+ inbuilt Widget. To import the package in your Flutter project follow the below guide.
Install Package from pub.dev :
https://pub.dev/packages/getwidget - Check the details about GetWidget Package.
Import full package:
Note: dependencies: getwidget: ^ 2.0.4
Keep playing with the pre-built UI components.
GetWidget Border is a simple solid line that acts as a surrounding line to any kind of widget. It is used as a wrapper that wraps the components inside it. GFBorder has many types in it and has customizable properties. Let us see one by one in the below sections.
How to Add Flutter Solid Border in Any Widget
Flutter Solid Border is a simple type of border that has a solid line around the widget as shown in the below image. This is a basic border used for many components. The appearance of the GFBorder can be customized using the GFBorder properties. You can use Flutter Border in Container Widget, Button or Card, etc. We can use the below code to build the Flutter Solid Border Widget.
Flutter Dashed Border Example
A Flutter dashed border is a customized type of border, that has a dashed line around the widget as shown in the below image.
Flutter Dotted Border Example
A Flutter dotted Border is one kind of border that has dotted lines around the components as shown in the below image.
GF Flutter Border Types
GFBorder has many types according to the parent widget. Some of them are rect, rRect, Oval, Circle. We can simply use them by assigning GFBorderType.rect or so.
It is one of the types of borders that gives a rectangle shape to the parent widget as shown in the below image. The below example codes give the rect border around the image.
GF Flutter Border has a property similar to the rectangle type of border. In this type, we will get a rounded-shaped corner as shown in the below image in the borders. The below code gives the rectangle border with slightly rounded corners.
GFBorder here will be an oval type as shown in the image. GFBorder property
GFBorderType.oval to display oval shape borders. The code for this is given below:
GF Flutter Border is also of type circle. This can be solid, dotted, and dashed. GFBorder property
GFBorderType.circle to display circular shape borders.
Below is the image of a dashed circular border with a child and the sample code:
