Installation

Add the Package

dependencies:
  flutter_gradients: ^1.0.0+3

Usage

Import the package

import 'package:flutter_gradients/flutter_gradients.dart';

How To Use

For LinearGradient

By default FlutterGradient will generates the LinearGradient.

   GradientType type: GradientType.linear;

    Container(
        width: 150,
        height: 150,
        decoration: BoxDecoration(
            shape: BoxShape.circle,
            gradient: FlutterGradient.warmFlame(),
        ),
    );

or

    Container(
        width: 150,
        height: 150,
        decoration: BoxDecoration(
            shape: BoxShape.circle,
            gradient: FlutterGradient.warmFlame(type: GradientType.linear),
        ),
    );

For RadialGradient

You can customize the follows values :

• center : The center of the gradient, as an offset into the (-1.0, -1.0) x (1.0, 1.0) square describing the gradient which will be mapped onto the paint box.
• radius : The radius of the gradient, as a fraction of the shortest side of the paint box.
• tileMode : How this gradient should tile the plane beyond the outer ring at radius pixels from the center.

   GradientType type: GradientType.radial;

    Container(
        width: 150,
        height: 150,
        decoration: BoxDecoration(
            shape: BoxShape.circle,
            gradient: FlutterGradient.warmFlame(
                type: GradientType.radial,
                center: Alignment.center,
                radius: 0.5,
                tileMode: TileMode.clamp,
           ),
        ),
    );

For SweepGradient

You can customize the follows values :

• center : The center of the gradient, as an offset into the (-1.0, -1.0) x (1.0, 1.0) square describing the gradient which will be mapped onto the paint box.
• startAngle : The angle in radians at which stop 0.0 of the gradient is placed.
• endAngle : The angle in radians at which stop 1.0 of the gradient is placed.
• tileMode : How this gradient should tile the plane beyond the outer ring at radius pixels from the center.

   GradientType type: GradientType.sweep;

    Container(
        width: 150,
        height: 150,
        decoration: BoxDecoration(
            shape: BoxShape.circle,
            gradient: FlutterGradient.warmFlame(
                type: GradientType.sweep,
                center: Alignment.center,
                startAngle: 0.0,
                endAngle: math.pi * 2,
                tileMode: TileMode.clamp,
            ),
        ),
    );
