ThemeResolver class abstract final

Resolves ThemeSpecs, memoising the last few so the same spec always yields the identical CalcThemeData (cheap ==, no rebuild churn).

Static Methods

clearMemo() → void

Clears the memo (tests).

prepare(ThemeSpec spec, Iterable<Size> cellSizes) → CalcThemeData

Resolves spec and builds its key-shape morphs for cellSizes ahead of a theme commit (call when the theme enters the prefetch queue).

resolve(ThemeSpec spec, {bool highContrast = false, GlassRendering glass = GlassRendering.standard}) → CalcThemeData

The CalcThemeData for spec. highContrast (platform setting) selects the plain theme's high-contrast variants; generated themes get their high-contrast treatment from the accessible lock instead.

Constants

memoCapacity → const int

Specs kept in the memo.
