14 | 15 | ## Usage 16 | 17 | ```dart 18 | FloodFillImage( 19 | imageProvider: AssetImage("assets/dog.jpg"), 20 | fillColor: Colors.amber, 21 | avoidColor: [Colors.transparent, Colors.black], 22 | ) 23 | ``` 24 | 25 | ## Parameters 26 | 27 | | Name | Type | Description | 28 | |---|---|---| 29 | | `imageProvider` | ImageProvider | The image to display via ImageProvider.
You can use `AssetImage` or `NetworkImage`. | 30 | | `fillColor` | Color | Color use for filling the area. | 31 | | `isFillActive` | bool | Set *false* if you want to disable on touch fill function.
Default value is *true*. | 32 | | `avoidColor` | List\ | List of color that determines to which `Color` is/are needed to be avoided upon touch.
**Note:** Nearest color shade is applied. | 33 | | `tolerance` | int | Set fill value *tolerance* that ranges from 0 to 100.
Default value is 8. | 34 | | `width` | int | Width of the image. Parent widget width will be prioritize if it's provided and less than the image width. | 35 | | `height` | int | Height of the image. Parent widget height will be prioritize if it's provided and less than the image height. | 36 | | `alignment` | AlignmentGeometry | Alignment of the image. | 37 | | `loadingWidget` | Widget | Widget to show while the image is being processed on initialization.
It uses `CircularProgressIndicator` by default. | 38 | | `onFloodFillStart` | Function(Offset position,Image image) | Callback function that returns the touch position and an `Image` from *dart:ui* when flood fill starts.
**Note:** Touch coordinate is relative to the image dimension. | 39 | | `onFloodFillEnd` | Function(Image image) | Callback function that returns an `Image` from *dart:ui* when flood fill ended. | 40
