AppOverlayScope class

Reprovê, no conteúdo de um OverlayEntry, os providers que o Overlay do root deixa para trás (ele vive ACIMA do tema/text-scale/DefaultTextStyle do app):

  • AppTheme — senão AppTheme.of lança "No AppTheme found in context";
  • text scale (via MediaQuery) — senão o overlay ignora o text scale (ex.: o TextScaleAddon do Widgetbook, que embrulha abaixo do Overlay);
  • DefaultTextStyle concreto — senão o texto cai no fallback do Flutter (sublinhado amarelo duplo "faltou Material").

Capture theme e textScaler no contexto do trigger (que está abaixo dos providers) e passe-os aqui dentro do OverlayEntry.
