Text to Path Maker
This is a pure Flutter and Dart package that allows you to convert text--both characters and icons--into paths. It can generate SVG path strings and Flutter
Path objects too.
Additionally, this package offers a bunch of methods you can use to animate those paths.
At the core of this package is a .ttf file parser, written in pure Dart. You can, if you want to, use it to read the font tables present in your TrueType font file.
You must always start by calling the
parseTTFAsset() method available in the
PMFontReader class to parse your font asset. Currently, only .ttf files are supported.
Once the font has been parsed, you'll have access to a
PMFont object. You can call its
generatePathForCharacter() method to convert any character into a
Path object. Note that this method expects you to pass the character code of the character.
Next, you'll want to use the
PMTransform.moveAndScale() method to position and scale the path. This is usually necessary because, by default, the paths can be quite large.
At this point, you can render the
Path object onto any
Canvas object. If you want to animate the path, however, you must call the
PMPieces.breakIntoPieces() method. This method splits the path into tiny paths, depending on the
precision you specify. These tiny paths, when rendered sequentially, will create the illusion of the character being drawn.
There's also a utility
PMPainter class, which extends the
CustomPainter class. You can use this to quickly render your animation using a

This package is still a work in progress. It works reasonably well with most fonts, but there's no guarantee that it will handle every single font you have. It has been tested with Roboto, FontAwesome, and Material Icons. If you find a bug, you can raise file it on this project's GitHub repository.
