What is the bug?

When I calculate tiles to check how many tiles for a specific region with zoom range from 1 to 21 then I get below error on IOS.

* thread #34, name = 'DartWorker', stop reason = EXC_RESOURCE RESOURCE_TYPE_MEMORY (limit=3072 MB, unused=0x0) frame #0: 0x0000000103dde4c0 Flutter`dart::BlockStack<64>::PopEmptyBlock() + 116 Flutter`dart::BlockStack<64>::PopEmptyBlock: -> 0x103dde4c0 <+116>: stp q0, q0, [x0, #0x10] 0x103dde4c4 <+120>: stp q0, q0, [x0, #0x30] 0x103dde4c8 <+124>: stp q0, q0, [x0, #0x50] 0x103dde4cc <+128>: stp q0, q0, [x0, #0x70] Target 0: (Runner) stopped. Lost connection to device. 

What is the expected behaviour?

It should give tiles count.

How can we reproduce this issue?

Use countties function from example. and select a large region and zoom level from 1 to 21.i.e Future<void> _countTiles() async { final DownloadProvider provider = Provider.of<DownloadProvider>(context, listen: false); if(provider.region != null) provider ..regionTiles = null ..regionTiles = await FMTC.instance('').download.check( provider.region.toDownloadable( provider.minZoom, provider.maxZoom, TileLayer(), ) ); }
