📺 Demo

🔩 Basic Demo

FSuper(
  margin: EdgeInsets.fromLTRB(12, 0, 12, 0),
  width: double.infinity,
  text: "This is FSuper!",
  backgroundColor: Color(0xffffc900),
),


FSuper(
  text: "En.. ",
  spans: [
    TextSpan(
        text: "FWidget",
        style: TextStyle(
          color: Color(0xffffc900),
          backgroundColor: Colors.black38,
          fontSize: 20,
        )),
  ...
  ],
),

FSuper The first part of the text is set through the text property, and related text style properties can be set. If you want to achieve rich text effects, you can pass a TextSpan array via the spans property.

Of course, by default, the properties you have not set for TextSpan will automatically inherit the text style configuration of FSuper.

By default, FSuper is able to adapt the text content size.

But you can still specify a specific size through the width, height properties. If you want the parent container to be full of components, you can set their value to double.infinity.

⚠️ You should never set the size of FSuper to double.infinity in an infinite parent container, because it really does not know how big it should be!

In addition, FSuper also provides maxWidth and maxHeight to assist in layout, which is useful in the case of an uncertain component size. Your components will never exceed their limits.

🖼 Corner & Stroke Demo

FSuper(
  width: 130,
  padding: EdgeInsets.only(top: 16, bottom: 16)
  text: 'Corner FSuper',
  backgroundColor: Color(0xffFF7043),
  corner: FCorner.all(12),
  cornerStyle: FCornerStyle.bevel,
),

FSuper(
  text: '音乐类型:流行音乐',
  padding: EdgeInsets.all(2),
  corner: FCorner.all(3),
  strokeColor: Color(0xffc2bfc2),
  strokeWidth: 1,
),

Using FSuper to declare a corner and border component is very simple.

Corners can be declared just by the corner property. A Corner object will describe the corners of the component. You can control each corner individually.

FSuper supports two types of corners:

• FCornerStyle.round：Rounded corners. This is what we need most of the time.

• FCornerStyle.bevel：bevel corners.

If you want a border, you only need to make StrokeWidth> 0 of FSuper. In addition, the strokeColor property allows you to describe the color of the border.

🔳 Gradient & Shadow Demo

FSuper(
  width: 280,
  height: 45,
  text: 'Search Flight',
  textAlignment: Alignment.center,
  corner: FCorner.all(23),
  gradient: LinearGradient(colors: [
    Color(0xfffed83a),
    Color(0xfffcad2c),
  ]),
),

The gradient property allows you to declare a gradient background for FSuper using a gradient object.

The gradient background will override the solid background color set by backgroundColor.

⚠️ Background priority：backgroundImage > gradient > backgroundColor.

FSuper(
  text: 'Overview',
  backgroundColor: Colors.white,
  padding: EdgeInsets.fromLTRB(6.0 + 18.0 + 6.0, 9, 9, 9),
  corner: Corner(rightTopCorner: 20, rightBottomCorner: 20),
  child1: Icon(
    Icons.subject,
    size: 18,
    color: Color(0xffa6a4a7),
  ),
  child1Alignment: Alignment.centerLeft,
  child1Margin: EdgeInsets.only(left: 3),
  shadowColor: Colors.black38,
  shadowBlur: 10,
  onClick: () {
    _showDialog(context, "Disco");
  },
),

If you are considering adding shadow effects to your components, using FSuper is a great choice.

🎈 Red Point Demo

FSuper(
  width: 60,
  height: 60,
  backgroundColor: Color(0xffeeeeee),
  corner: FCorner.all(6),
  redPoint: true,
  readPointTextStyle: TextStyle(fontSize: 20.0),
  redPointText: "红包",
),

Using FSuper can be very simple to achieve the common Red Point effect. Just configure redPoint: true.

In addition, you can add arbitrary text content to the Red Point (it is really convenient) and set its position.

⚠️ The (0,0) position of the Red Point is in the upper right corner of FSuper.

One-stop service to meet all your needs.

🧸 Child Widget

FSuper(
    width: double.infinity,
    padding: EdgeInsets.fromLTRB(
        (16.0 + 25.0 + 12), 8, (0.0 + 8.0), 8),
    margin: EdgeInsets.fromLTRB(10, 10, 10, 0),
    corner: FCorner.all(6),
    backgroundColor: Color(0xfffff0e7),
    strokeColor: Color(0xfffee0cd),
    strokeWidth: 1,
    text: '警告提示的文案',
    textAlignment: Alignment.centerLeft,
    textAlign: TextAlign.left,
    spans: [
      ...
    ],
    child1: Transform.rotate(
      angle: pi,
      child: Icon(
        Icons.info,
        size: 25,
        color: Color(0xfffd6721),
      ),
    ),
    child1Alignment: Alignment.centerLeft,
    child1Margin: EdgeInsets.fromLTRB(16, 0, 0, 0),
    child2: Icon(
      Icons.close,
      size: 15,
      color: Colors.black38,
    ),
    child2Alignment: Alignment.topRight,
    child2Margin: EdgeInsets.fromLTRB(0, 8, 12, 0),
    onChild2Click: () {
      _showDialog(context, "关闭警告⚠️");
    },
  ),

In FSuper, two child components can be declared by child1, child2. You can specify their location and declare a click event.

This will greatly increase development speed in some common and complex layouts. Especially in the scenario where the size of one component is small and uncertain, and the other component determines the position based on its size, FSuper handles everything.

The effects of these components in the picture only need one FSuper component to complete.

🍭 Neumorphism 风格

FSuper(

  /// 开启 Neumorphism 支持
  ///
  /// Turn on Neumorphism support
  isSupportNeumorphism: true,

  /// 配置光源方向
  ///
  /// Configure light source direction
  lightOrientation: lightOrientation,

  /// 配置暗部阴影
  ///
  /// Configure dark shadows
  shadowColor: Colors.black87,

  /// 配置亮部阴影
  ///
  /// Configure highlight shadow
  highlightShadowColor: Colors.white24,

  /// 是否呈浮起视效
  ///
  /// Whether it is floating visual effect
  float: false,
  shadowOffset: Offset(0.0, 1.0),
  width: 50,
  height: 50,
  backgroundColor: Color(0xff28292f),
  corner: FCorner.all(40),
  child1: Icon(
    Icons.star,
    color: Color(0xfffff176),
    size: 23,
  ),
),

FButton brings an incredible, ultra-high texture Neumorphism style to developers.

Developers only need to configure the isSupportNeumorphism parameter to enable and disable the Neumorphism style.

If you want to adjust the style of Neumorphism, you can make subtle adjustments through several attributes related to Shadow, among which:

• shadowColor: configure the shadow of the shadow

• highlightShadowColor: configure highlight shadow

FButton also provides lightOrientation parameters, and even allows developers to adjust the care angle, and has obtained different Neumorphism effects.

Through the float parameter, developers can easily switch between floating visual effect and recessed visual effect.

🎞 More Demo

Do not be surprised, the effects in the figure are all achieved with FSuper.

The design of the sub-components makes FSuper a qualitative leap in flexibility, and most of the complex views are capable.

For example, the chat bubble in the picture does not need to use the background picture, just use FSuper to achieve it. This makes such components extremely flexible and easy to modify.

FSuper(
  maxWidth: 220,
  textAlign: TextAlign.left,
  text: "I'm created by FSuper 😄",
  padding: EdgeInsets.only(
      left: 12, right: 12, top: 15, bottom: 15),
  backgroundColor: Color(0xffa5ed7e),
  corner: FCorner.all(6),
  child1: Transform.rotate(
    angle: pi / 4,
    child: FSuper(
      width: 10,
      height: 10,
      backgroundColor: Color(0xffa5ed7e),
      corner: FCorner.all(1.5),
    ),
  ),
  child1Alignment: Alignment.topRight,
  child1Margin: EdgeInsets.only(right: -4, top: 20),
  shadowColor: Color(0xffa5ed7e),
  shadowBlur: 5,
),
