flutter::testing::TestAssetResolver Class Reference

Inheritance diagram for flutter::testing::TestAssetResolver:

Public Member Functions
	TestAssetResolver (bool valid, AssetResolver::AssetResolverType type)
bool	IsValid () const override
bool	IsValidAfterAssetManagerChange () const override
	Certain asset resolvers are still valid after the asset manager is replaced before a hot reload, or after a new run configuration is created during a hot restart. By preserving these resolvers and re-inserting them into the new resolver or run configuration, the tooling can avoid needing to sync all application assets through the Dart devFS upon connecting to the VM Service. Besides improving the startup performance of running a Flutter application, it also reduces the occurrence of tool failures due to repeated network flakes caused by damaged cables or hereto unknown bugs in the Dart HTTP server implementation.

GetAsMapping()

std::unique_ptr< fml::Mapping > flutter::testing::TestAssetResolver::GetAsMapping ( const std::string &  asset_name ) const

inlineoverridevirtual

Implements flutter::AssetResolver.

Definition at line 251 of file shell_unittests.cc.

                                                  {
    return nullptr;
  }

GetAsMappings()

std::vector< std::unique_ptr< fml::Mapping > > flutter::testing::TestAssetResolver::GetAsMappings ( const std::string &  asset_pattern, const std::optional< std::string > &  subdir  ) const

inlineoverridevirtual

Same as GetAsMapping() but returns mappings for all files who's name matches a given pattern. Returns empty vector if no matching assets are found.

Parameters

[in]	asset_pattern	The pattern to match file names against.
[in]	subdir	Optional subdirectory in which to search for files. If supplied this function does a flat search within the subdirectory instead of a recursive search through the entire assets directory.

Returns

Returns a vector of mappings of files which match the search parameters.

GetType()

AssetResolver::AssetResolverType flutter::testing::TestAssetResolver::GetType ( ) const

inlineoverridevirtual

Gets the type of AssetResolver this is. Types are defined in AssetResolverType.

Returns

Returns the AssetResolverType that this resolver is.

Implements flutter::AssetResolver.

Definition at line 249 of file shell_unittests.cc.

{ return type_; }

IsValid()

bool flutter::testing::TestAssetResolver::IsValid ( ) const

Implements flutter::AssetResolver.

{ return true; }

IsValidAfterAssetManagerChange()

bool flutter::testing::TestAssetResolver::IsValidAfterAssetManagerChange ( ) const

inlineoverridevirtual

Certain asset resolvers are still valid after the asset manager is replaced before a hot reload, or after a new run configuration is created during a hot restart. By preserving these resolvers and re-inserting them into the new resolver or run configuration, the tooling can avoid needing to sync all application assets through the Dart devFS upon connecting to the VM Service. Besides improving the startup performance of running a Flutter application, it also reduces the occurrence of tool failures due to repeated network flakes caused by damaged cables or hereto unknown bugs in the Dart HTTP server implementation.

Returns

Returns whether this resolver is valid after the asset manager or run configuration is updated.

Implements flutter::AssetResolver.

Definition at line 247 of file shell_unittests.cc.

{ return valid_; }

operator==()

bool flutter::testing::TestAssetResolver::operator== ( const AssetResolver &  other ) const
