Flutter Material Color Picker #
Material Color picker is a Flutter widget, that can be customizable.
By default, it's Material Colors, but you can define your own colors.
You can also use CircleColor widget to display color in your app.
Example, you can set the color picker in a dialog and display the selected color in a ListTile, for settings.
How to use it #
These examples use a static color for 'selectedColor', but you can use a variable (state)
Add to your Flutter project #
You just need to add flutter_material_color_picker as a dependency in your pubspec.yaml file.
flutter_material_color_picker: ^1.2.0

allowShades: false, // default true
onMainColorChange: (ColorSwatch color) {
// Handle main color changes
},
selectedColor: Colors.red

If allowShades is set to false then only main colors will be shown and allowed to be selected.
onColorChange will not be called, use onMainColorChange instead.
Custom colors #
In this example, custom colors are a list of Material Colors (class who extend of ColorSwatch).
But you can create your own list of ColorSwatch.
MaterialColorPicker(
onColorChange: (Color color) {
// Handle color changes
},
selectedColor: Colors.red,
colors: [
Colors.red,
Colors.deepOrange,
Colors.yellow,
Colors.lightGreen
],
