 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.

Member Function Documentation

◆ GetAsMapping()

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

Implements flutter::AssetResolver.

Definition at line 287 of file shell_unittests.cc.

288 {
289 return nullptr;
290 }

◆ 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_patternThe pattern to match file names against.
[in]subdirOptional 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

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

Returns
Returns the AssetResolverType that this resolver is.

Implements flutter::AssetResolver.

285{ return type_; }

◆ IsValid()

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

Implements flutter::AssetResolver.

280{ 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 283 of file shell_unittests.cc.

283{ return valid_; }

◆ operator==()

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