expansionMemory property

int expansionMemory
final

Maximum number of entries in _rememberedExpansion. When exceeded, the oldest are evicted: Dart maps iterate in first-insertion order, and re-recording an existing key does not move it, so eviction is FIFO by when a key was FIRST remembered. 0 disables the memory entirely: nothing is remembered or restored across remove/re-add.

Implementation

final int expansionMemory;
