BindingScope class

A widget that installs a GetX Bindings on mount and cleans up only what it created on dispose.

Typical usage:

BindingScope(
  binding: HomeBinding(), // calls DI.* inside
  child: HomePage(),
)

Lifecycle:

  • initState: swaps DI._active to a new internal recorder and executes binding.dependencies(). Any DI.put/lazyPut/putAsync/create inside are recorded as owned by this scope. Then it restores the previous recorder (so nested scopes don’t steal each other’s ownership).
  • dispose: asks the recorder to clean up:
    • waits briefly for in-flight async
    • attaches late-delete hooks to still-running installs
    • deletes owned registrations in reverse order
