text_x_arc
The Helper for draws Arc Text on canvas
Inspired from flutter_arc_text.
If you just need a way to draw text along an arc, just go with flutter_arc_text.
This package was develop for my special use case so maybe it not suits you.
Consider this package if you need:
- draw text along an arc on canvas
- care about start angle and end angle
- remove all letter out of range (from start angle to end angle)
- center align only when the text shorter than the arc
- customize letter spacing
- tracking what happens on the canvas when draw an arc text.
Basic usage
import 'package:flutter/material.dart';
import 'package:flutter/widgets.dart';
import 'package:text_x_arc/text_x_arc.dart';
main() {
runApp(CustomPaint(
painter: MyPainter(),
));
}
class MyPainter extends CustomPainter {
@override
void paint(Canvas canvas, Size size) {
final centerPos = Offset(size.width / 2, size.height / 2);
TextPainter textPainter = TextPainter(
textAlign: TextAlign.justify, textDirection: TextDirection.ltr);
XArcTextDrawer.draw(
canvas: canvas,
centerPos: centerPos,
radius: 200,
text:
'Without requirements or design, programming is the art of adding bugs to an empty text file.',
textStyle: TextStyle(color: Colors.black, fontSize: 20),
textPainter: textPainter);
}
@override
bool shouldRepaint(covariant CustomPainter oldDelegate) => true;
}
