Help with resolutions

[fusionconsulting]

I have a map tile set with 3 zoom levels, 0 being the largest and 2 being the smallest. I have setup the map in the same manner as the CRS examples:

final resolutions = _tileProvider.zoomLevels.map<double>((level) => level.resolution).toList();

Resolution is calculated as meters per tile / tile pixel size to give meters per pixel as per the documentation.

My resolutions look like this:

0.416
0.833
1.666

My maxZoom is set to resolutions.length - 1 which is 2.0.

When I attempt to zoom, I get an error at crs.zoom():

RangeError (RangeError (length): Invalid value: Not in inclusive range 0..2: 3)

It appears to be trying to zoom beyond the maximum zoom but I can't see what I need to change to prevent this. I have tried reducing the maxZoom to no avail. I have tried switching zoomReverse on and adjusting the zoomOffset which don't seem to have any effect.

Any pointers on what I am doing wrong would be much appreciated.
