@astheras it seems the code is not the root cause of error. at http://localhost:49699/packages/loading_indicator/src/indicators/triangle_skew_spin.dart.lib.js:7687:51 but the code is indicatorType: Indicator.ballBeat,

[tigrenok00]

It happens to me all the time as well, any solution?

[TinoGuo]

can u provide minimum reproduce code?
