[dependabot]

Bumps provider from 5.0.0 to 6.0.3.

Changelog

Sourced from provider's changelog.

6.0.3

• fix late initialization error when using debugPrintRebuildDirtyWidgets
• slightly reduced the binary size of release mode applications using provider
• Fix typos in the error message of ProviderNotFoundException
• improve performances for reading providers (thanks to @​jiahaog)

6.0.2

Added error details for provider that threw during the creation (thanks to @​jmewes)

6.0.1

Removed the assert that prevented from using ChangeNotifierProvider with notifiers that already had listeners.

• Breaking: It is no longer possible to define providers where their only difference is the nullability of the exposed value:

  MultiProvider(
    providers: [
      Provider<Model>(...),
      Provider<Model?>(...)
    ]
  )

  Before, when defining those providers, doing context.watch<Model> vs context.watch<Model?> would point to a different provider. Now, both will always point to the deepest provider (in this example Provider<Model?>).

  That fixes issues where a common developer mistake is to define a provider as Model? but try to read it as Model. Previously, that would give a ProviderNotFoundException. Now, this will correctly resolve the value.

  That also helps large codebase migrate to null-safety progressively, as they would temporarily contain both null-safe and unsound code. Previously, unsound code would be unable to read a provider defined as Provider<Model?>, as Model? is not a valid syntax. With this change, this is now feasible.

• It is now possible to read a provider without throwing a ProviderNotFoundException if the provider is optional.

  To do so, when calling context.watch/context.read, make the generic type nullable. Such that instead of:
