"FlSpot.nullSpot' at the end of the LineChartBarData not working

hello man nice work you doing here i found this bug with using 'FlSpot.nullSpot' at the end of the chart, it the chart just ignores it like it does'nt exist but if u put a regular flSSpot after it it works fine, here is the code to produce the bug `
[
const FlSpot(0, 0),
const FlSpot(1, 0),
const FlSpot(2, 2),
const FlSpot(3, 3),
FlSpot.nullSpot,
FlSpot.nullSpot,
FlSpot.nullSpot,
],`using this code produces this
and this code with adding a regular flspot after the null ones "the desired output" `
[
const FlSpot(0, 0),
const FlSpot(1, 0),
const FlSpot(2, 2),
const FlSpot(3, 3),
FlSpot.nullSpot,
FlSpot.nullSpot,
const FlSpot(6, 5),
];`
thanks in advance ;)

Start by reproducing the issue with the provided FlSpot.nullSpot lists in a LineChartBarData and compare the two rendered outputs. Trace the LineChart and FlSpot.nullSpot handling to find why trailing null spots are ignored. Done means consecutive null spots at the end produce the same intended chart gap as when followed by a regular FlSpot.
