Could not find context {}

Error message

Could not find context {}

What it means

consume_context looked up a context of the requested type in the current scope's runtime and found none. A provider for that type must exist in an ancestor scope (via provide_context) before it can be consumed; a missing or differently-typed provider causes this failure.

Solutions

1. Provide the context in an ancestor component with use_context_provider before consuming it with use_context or try_use_context.
