GlobalKey _textKey -- should not be a global

[awhitford]

This looks wrong:

Animated-Text-Kit/lib/src/text_liquid_fill.dart

Line 4 in d4c3346

GlobalKey _textKey;

Note that it is being set by _TextLiquidFillState.initState:

Animated-Text-Kit/lib/src/text_liquid_fill.dart

Lines 78 to 82 in d4c3346

	@override
	void initState() {
	super.initState();
	_textKey = GlobalKey();

I'm guessing that _textKey should be a member of the _TextLiquidFillState class. However, I suspect that this was moved to expose it WavePainter:

Animated-Text-Kit/lib/src/text_liquid_fill.dart

Lines 165 to 181 in d4c3346

	class WavePainter extends CustomPainter {
	Animation<double> waveAnimation;
	double percentValue;
	double boxHeight;
	Color waveColor;
	WavePainter(
	{this.waveAnimation, this.percentValue, this.boxHeight, this.waveColor});
	@override
	void paint(Canvas canvas, Size size) {
	double width = (size.width != null) ? size.width : 200;
	double height = (size.height != null) ? size.height : 200;
	Paint wavePaint = Paint()..color = waveColor;
	RenderBox textBox = _textKey.currentContext.findRenderObject();

However, it should simply be passed.

The concern/risk is that two instances of TextLiquidFill will collide/overwrite this global.
