imaNNeo/fl_chart 0.51.0 on GitHub

FEATURE (by @imaNNeoFighT): Add SideTitleWidget to help you use it in [SideTitles.getTitlesWidget]. It's a wrapper around your widget. It keeps your provided child widget close to the chart. It has angle and space properties to handle margin and rotation. There is a axisSide property that you should fill, it has provided to you in the MetaData object. Check the below sample:

getTitlesWidget: (double value, TitleMeta meta) {
  return SideTitleWidget(
    axisSide: meta.axisSide,
    space: 8.0,
    angle: 0.0,
    child: const Text("This is your widget"),
  );
},

IMPROVEMENT (by @imaNNeoFighT): Fix default LineChart interval issue on small view sizes, #909.
