This happens often on Testnet because the network fee is always 1.0 sat/byte.

It's breaking because the fee slider values require a min , max, and value and they don't meet the conditions.

Those values get set in the slider.dart file based on the feeCubit values.

[i5hi]

You can temporarily fix this by hard coding the min (absolute fee) value to 1.

This will temporarily create another bug where if you use low levels on the slider the fee will be too low and it will break on the next step giving a min relay fee error.

Also, generally the way we do fees requires some more attention.

Its very naive right now.

1 conf network estimate for fast
value/2 for medium
1 sat/byte for slow

in this error
[log] 'package:flutter/src/material/slider.dart': Failed assertion: line 147 pos 15: 'value >= min && value <= max': is not true.

We use medium fee for as the starting value for the slider which ends up being 0.5 while min and max are both 1.

This will be fixed in the next release by the 28th.

Updated in dev branch. Will merge by the end of the week.
