flutter_guitar_tabs's Issues

An error because of "Null check operator used on a null value"

Hey @joranmulderij I think I found an error when the e string is muted on the tab as X, here's the message I got from the terminal

The following _CastError was thrown during paint():
Null check operator used on a null value

The relevant error-causing widget was:
  CustomPaint

The following RenderObject was being processed when the exception was fired: RenderCustomPaint#254e2:
  creator: CustomPaint ← ConstrainedBox ← Container ← Column ← FlutterGuitarTab ← Column ←
    Consumer<ChordViewModel> ← ChordScreen ← Offstage ← Stack ← KeyedSubtree-[GlobalKey#f469c] ←
    _BodyBuilder ← ⋯
  parentData: <none> (can use size)
  constraints: BoxConstraints(w=180.0, h=150.0)
  size: Size(180.0, 150.0)
  painter: _MyPainter#24b6b()
This RenderObject has no descendants.```

I tried to fix it myself, but it seems to be I'm at my limit and I can't fix it.

Where should I get all the tabs data?

Where should I get all the tabs data? I am using flutter_chord and when user click the chord I want to show the tabs. May I know where can I get all the tabs data?

The grid does not appear in the rendering

I created a basic widget following the instructions but the grid does not appear during rendering.

My code is like:

[other imports...]

import 'package:flutter_guitar_tabs/flutter_guitar_tabs.dart';

class NewCustomWidget extends StatelessWidget {
  final double? width;
  final double? height;

  const NewCustomWidget({
    Key? key,
    this.width,
    this.height,
  }) : super(key: key);
  @override
  Widget build(BuildContext context) {
    return FlutterGuitarTab(
      name: 'Dm',
      tab: 'x 0 0 2 3 1',
    );
  }
}

We need a fret number.

How the use will recognize the fret number if the chords is on more than the 5th fret ?

int to double conversion error on Android

On android, an exception gets thrown when building the widgets:

The following _TypeError was thrown during paint():
type 'int' is not a subtype of type 'double'

The relevant error-causing widget was: 
  TabWidget file:///C:/Users/joran/Documents/GitHub/worshipleaderapp/lib/SongRoute/ChordTabContent.dart:178:27
When the exception was thrown, this was the stack: 
#0      _MyPainter.drawFretGrid (package:flutter_guitar_tabs/flutter_guitar_tabs.dart:270:15)
#1      _MyPainter.draw (package:flutter_guitar_tabs/flutter_guitar_tabs.dart:356:10)
#2      _MyPainter.paint (package:flutter_guitar_tabs/flutter_guitar_tabs.dart:468:5)
#3      RenderCustomPaint._paintWithPainter (package:flutter/src/rendering/custom_paint.dart:564:13)
#4      RenderCustomPaint.paint (package:flutter/src/rendering/custom_paint.dart:605:7)

How to show what fret bar chord is played on

This may be related to #3 , but would it be possible to add the ability to show that he first fret in the tab is the 5th fret for example? All of this would be solvable by allowing fret numbers to be added to the dots in the chart though.

Null Safety?

Hi mate great package , creating an app and thinking on integrating this any chance you working on a version with null safety?

Also would be great to be able to style the font colors and background
