ImageVector.Builder


Builder used to construct a Vector graphic tree. This is useful for caching the result of expensive operations used to construct a vector graphic for compose. For example, the vector graphic could be serialized and downloaded from a server and represented internally in a ImageVector before it is composed through rememberVectorPainter The generated ImageVector is recommended to be memoized across composition calls to avoid doing redundant work
