Usage #
To apply the API, import package:free_form_text/free_form_text.dart, create a Future<FreeFormText> and use it in a FutureBuilder that includes
a CustomPaint
widget as illustrated below. The actual painting is done in a
CustomPainter.
Create a FreeFormText object:
FreeFormText text = FreeFormText(
label: 'Lorem ipsum dolor sit amet.',
context: context,
style: const TextStyle(
fontSize: 16,
color: Colors.black,
wordSpacing: 2.0,
letterSpacing: 0.5,
fontWeight: FontWeight.bold));
Future<FreeFormText> textFuture = text.layout();

Then paint it in a CustomPainter:
class ExampleTextPainter extends CustomPainter {
FreeFormText text;
ExampleTextPainter(this.text);
@override
void paint(Canvas canvas, Size size) {
var painter = FreeFormTextPainter(canvas);
painter.paintText(
text: text, offset: const Offset(50.0, 200.0), angle: 30.0);
}
@override
bool shouldRepaint(covariant CustomPainter oldDelegate) {
return false;
}
}
