TinyLineChart class

A Widget that paints a simple line chart.

It is ideal for sparkline charts.

The data can be provided by a list of coordinates that can be represented by either flutter's Offset or by vector_math's Vector2.

The line will be draw using dataPoints as vertices. The data space to be painted by the chart can be bounded by passing the limits to options.

For example, if options.xMaxLimit is passed, the line chart will be painted in such a way that any data point beyond that limit will not be painted.

If both width and height are passed, the chart will try to keep aspect ratio.
