#This is the code the only problem is that pervious color is being disappear. And i doesnt want that to happen. I want to pick color like multiple color and color colors in different section of house
When you change Shape color you do not hold this value. Then you select another shape and old shape goes to default color.
I assume that, you select color by button, then click shapes and fill those shapes with selected color. And if you click second times to shape with same color then shape should return to its default color. Otherwise we never go back to default color if default colors not on buttons.
1- Change your Shape class. We need selected color, isSelected parameter, default color on shape.
class Shape {
Shape(strPath, this.label, this.defaultColor, this.isSelected, this.selectedColor)
: _path = parseSvgPathData(strPath);
final Color? defaultColor;
bool isSelected=false;
Color? selectedColor;
...
example of Shape
final _shapes = [
Shape(_data[0], '0', const Color(0xffacd266),false, null),
Shape(_data[1], '1', const Color(0x000fffff),false, null),
...
2- Do not use setState on your color choose TextButtons, we do not need this, we just need to set _fillColor thats all.
TextButton(
onPressed: () { _fillColor = Colors.brown; },
...
3- change Paint function and assign isSelected and selectedColor on Shape.
canvas
..clipRect(Offset.zero & size)
..drawColor(Colors.white, BlendMode.src);
List<Path>? selectedShape;
for (var shape in _shapes) {
final path = shape._transformedPath;
selected = path!.contains(_notifier.value);
if(selected == true){
// if shape selected before and try to fill with same color again,
// i assume that this means back to the default color,
// otherwise we never go back to default color if default colors not on buttons
if(shape.isSelected == true && shape.selectedColor == _fillColor){
shape.isSelected = false;
shape.selectedColor = null;
}else{
shape.isSelected = selected;
shape.selectedColor = _fillColor;
}
}
_paint
// if selected then selected color otherwise default color
..color = (shape.isSelected == true ? shape.selectedColor : shape.defaultColor)!
..style = PaintingStyle.fill;
canvas.drawPath(path, _paint);
I tested it and it seems to work. Let me know if it is work or not :)
