🔩 Basic Demo #
// FButton #1
FButton(
height: 40,
alignment: Alignment.center,
text: "FButton #1",
style: TextStyle(color: Colors.white),
color: Color(0xffffab91),
onPressed: () {},
)
// FButton #2
FButton(
padding: const EdgeInsets.fromLTRB(12, 8, 12, 8),
text: "FButton #2",
style: TextStyle(color: Colors.white),
color: Color(0xffffab91),
corner: FCorner.all(6.0),
)
// FButton #3
FButton(

color: Color(0xffF8AD36),
/// set disable Color
disabledColor: Colors.grey[300],
corner: FCorner.all(6.0),
)
By simply configuring text
and onPressed
, you can construct an available FButton.
If onPressed
is not set, FButton will be automatically recognized as not unavailable. At this time, ** FButton ** will have a default unavailable status style.
You can also freely configure the style of FButton when it is not available via the disabledXXX
attribute.

Through the loading
attribute, you can configure Loading effects for ** FButton **.
When FButton is in Loading state, FButton will enter an unavailable state, onPress will no longer be triggered, and unavailable styles will also be applied.
At the same time loadingText
will overwrite text
if it is not null.
The click start Loading effect can be achieved through the clickLoading
attribute.
The position of loading
will be affected by the imageAlignment
attribute.
When hideTextOnLoading: true
, if FButton is in loading
state, its text will be hidden.
Through loadingWidget
, developers can set completely customized loading styles.
Shadow #
FButton(
width: 200,
text: "Shadow",
textColor: Colors.white,
color: Color(0xffffc900),
onPressed: () {},
clickEffect: true,
corner: FCorner.all(28),
/// 配置阴影颜色
///
/// set shadow color
shadowColor: Colors.black87,
/// 设置组件高斯与阴影形状卷积的标准偏差。
///
/// Sets the standard deviation of the component's Gaussian convolution with the shadow shape.
shadowBlur: _shadowBlur,
),
FButton allows you to configure the color, size, and position of the shadow.
🍭 Neumorphism Style #
FButton(
/// 开启 Neumorphism 支持
///
/// Turn on Neumorphism support
isSupportNeumorphism: true,
/// 配置光源方向
///
/// Configure light source direction
lightOrientation: lightOrientation,
/// 配置亮部阴影
///
/// Configure highlight shadow
highlightShadowColor: Colors.white,
/// 配置暗部阴影
///
/// Configure dark shadows
shadowColor: mainShadowColor,
strokeColor: mainBackgroundColor,
strokeWidth: 3.0,
width: 190,
height: 60,
text: "FWidget",
style: TextStyle(
color: mainTextTitleColor, fontSize: neumorphismSize_2_2),
alignment: Alignment.center,
color: mainBackgroundColor,
...
)
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.
