Code Review

This pull request updates several packages: animations adds custom shadow support to OpenContainer; camera_android_camerax bumps CameraX to 1.6.0; go_router improves URI normalization for paths without leading slashes; and go_router_builder introduces support for custom types in TypedQueryParameter using custom encoder, decoder, and compare functions. Additionally, webview_flutter_wkwebview reverts a recent change to resolve build errors, and the repository tool script is refactored. Review feedback identifies a potential type mismatch in the generated decoder for non-nullable parameters and suggests simplifying the generated encoder by removing redundant null checks.

The generated code for custom decoders will fail to compile if the parameter is non-nullable and has no default value. This is because stateValueAccess (which resolves to state.uri.queryParameters['...'] or state.pathParameters['...']) returns a nullable String?, but the custom decoder function likely expects a non-nullable String. Adding a null-assertion operator (!) ensures the types match and provides a runtime error if a required parameter is missing.

Suggested change

	if (!element.type.isNullableType && !element.hasDefaultValue) {
	decoded = '$annotatedDecoder($stateValueAccess)';
	} else {
	if (!element.type.isNullableType && !element.hasDefaultValue) {
	decoded = '$annotatedDecoder($stateValueAccess!)';
	} else {

The generated code for custom encoders contains a redundant null check when the field is nullable. The caller in _GoRouteMixin already wraps the encoding logic in an if (field != null) block for nullable parameters. Simplifying this to return the encoded expression directly (with a null-assertion for nullable fields to satisfy the type system) results in cleaner generated code.

  final String? annotatedEncoder = element.encoder;
  if (annotatedEncoder != null) {
    final fieldAccess = '$selfFieldName.${element.displayName}';
    final bool isNullable = element.returnType.isNullableType;
    return '$annotatedEncoder($fieldAccess${isNullable ? '!' : ''})';
  }
