FormBuilderSignaturePad initialValue issue

[janardhanmupparaju]

I am trying to give initial value to FormBuilderSignaturePad but it is not displaying old signature.

this is code
final GlobalKey _fbKey = GlobalKey();

Container(
child: FormBuilder(
key: _fbKey,
autovalidate: true,
child: FormBuilderSignaturePad(
initialValue: Singleton.signatureImage == null
? null
: Singleton.signatureImage,
decoration: InputDecoration(
labelText: "Signature", border: InputBorder.none),
penColor: Colors.blue,
onChanged: (value) async {
setState(() {
Singleton.signatureImagePath = value;
});
},
attribute: "signature",
height: 100,
),
));

Hi @janardhanmupparaju,
This is a known issue. The problem is that the underlying package we use for the field expects a list of points as the input and not an image.
Currently, I haven't figured out a way to convert an image to a list of points for the initialValue to work.

Fixed in latest versions of the library
