Bloc Heim

VSCode extension which drastically reduces bloc-related boilerplate code for Flutter projects.

Features

Command bloc-heim.createBloc for equatable-based bloc template, which includes:

• Main bloc file.
• Bloc state file — one class with status field, with respect to official bloc naming convention.
• Bloc events file.

Command and code action bloc-heim.addStateProperty:

• Adds a new property snippet to bloc state class.
• Works only for status-based state classes.

Wrappers and code-actions for all bloc Flutter widgets:

• BlocProvider: bloc-heim.wrapWithBlocProvider
• MultiBlocProvider: bloc-heim.wrapWithMultiBlocProvider
• BlocBuilder: bloc-heim.wrapWithBlocBuilder
• BlocSelector: bloc-heim.wrapWithBlocSelector
• BlocListener: bloc-heim.wrapWithBlocListener
• MultiBlocListener: bloc-heim.wrapWithMultiBlocListener
• BlocConsumer: bloc-heim.wrapWithBlocConsumer
• RepositoryProvider: bloc-heim.wrapWithRepositoryProvider
• MultiRepositoryProvider: bloc-heim.wrapWithMultiRepositoryProvider

Snippets:

• blocevent - generates new bloc event class with placeholders.
• onblocevent - generates code for bloc`s event handler.
• emitblocstate - generates bloc`s emit code with state.copyWith included.
• readbloc - generates code which reads bloc from context.
• readblocadd - generates code which reads bloc from context and adds bloc event.

Usage
