of static method

FunctionsAdapter? of(
  1. BuildContext context
)

By passing context, the FunctionsAdapter set in FunctionsAdapterScope can be obtained.

If the ancestor does not have FunctionsAdapterScope, an error will occur.

contextを渡すことによりFunctionsAdapterScopeで設定されたFunctionsAdapterを取得することができます。

祖先にFunctionsAdapterScopeがない場合はエラーになります。

Implementation

static FunctionsAdapter? of(BuildContext context) {
  final scope = context
      .getElementForInheritedWidgetOfExactType<_FunctionsAdapterScope>();
  assert(
    scope != null,
    "FunctionsAdapterScope is not found. Place [FunctionsAdapterScope] widget closer to the root.",
  );
  return (scope?.widget as _FunctionsAdapterScope?)?.adapter;
}
