AssertionErrorflask.debughelpers.DebugFilesKeyError - Raised from request.files during debugging. The idea is that it can provide a better error message than just a generic KeyError/BadRequest.flask.debughelpers.FormDataRoutingRedirect - This exception is raised by Flask in debug mode if it detects a redirect caused by the routing system when the request method is not GET, HEAD or OPTIONS. Reasoning: form data will be dropped.flask.debughelpers.UnexpectedUnicodeError - Raised in places where we want some better error reporting for unexpected unicode or binary data.click.Groupflask.cli.AppGroup - This works similar to a regular click ~click.Group but it changes the behavior of the command decorator so that it automatically wraps the functions in with_appcontext.flask.cli.FlaskGroup - No summaryclick.ParamTypeflask.cli.CertParamType - Click option type for the --cert option. Allows either an existing file, the string 'adhoc', or an import for a ~ssl.SSLContext object.click.Pathflask.cli.SeparatedPathType - Click option type that accepts a list of values separated by the OS's path separator (:, ; on Windows). Each value is validated as a click.Path type.click.testing.CliRunnerflask.testing.FlaskCliRunner - A ~click.testing.CliRunner for testing a Flask app's CLI commands. Typically created using ~flask.Flask.test_cli_runner. See :ref:`testing-cli`.click.UsageErrorflask.cli.NoAppException - Raised if an application cannot be found or loaded.collections.abc.MutableMappingflask.sessions.SessionMixin - Expands a basic dictionary with session attributes.flask.sessions.SecureCookieSession - Base class for sessions based on signed cookies.flask.sessions.NullSession - Class used to generate nicer error messages if sessions are not available. Will still allow read-only access to the empty session but fail on setting.dictflask.config.Config - Works exactly like a dict but provides ways to fill it from files or special dictionaries. There are two common patterns to populate the config.flask.blueprints.BlueprintSetupState - No summaryflask.cli.DispatchingApp - No summaryflask.cli.ScriptInfo - No summaryflask.config.ConfigAttribute - Makes an attribute forward to the configflask.ctx._AppCtxGlobals - A plain object. Used as a namespace for storing data during an application context.flask.ctx.AppContext - No summaryflask.ctx.RequestContext - No summaryflask.json.tag.JSONTag - Base class for defining type tags for TaggedJSONSerializer.flask.json.tag.PassDict - Undocumentedflask.json.tag.PassList - Undocumentedflask.json.tag.TagBytes - Undocumentedflask.json.tag.TagDateTime - Undocumentedflask.json.tag.TagDict - Tag for 1-item dicts whose only key matches a registered tag.flask.json.tag.TagMarkup - Serialize anything matching the ~markupsafe.Markup API by having a __html__ method to the result of that method. Always deserializes to an instance of ~markupsafe.Markup.flask.json.tag.TagTuple - Undocumentedflask.json.tag.TagUUID - Undocumentedflask.json.tag.TaggedJSONSerializer - Serializer that uses a tag system to compactly represent objects that are not JSON types. Passed as the intermediate serializer to itsdangerous.Serializer.flask.scaffold.Scaffold - Common behavior shared between ~flask.Flask and ~flask.blueprints.Blueprint.flask.app.Flask - No summaryflask.blueprints.Blueprint - Represents a blueprint, a collection of routes and other app-related functions that can be registered on a real application later.flask.sessions.SessionInterface - No summaryflask.sessions.SecureCookieSessionInterface - The default session interface that stores sessions in signed cookies through the itsdangerous module.flask.signals._FakeSignal - No summaryflask.signals.Namespace - Undocumentedflask.views.View - No summaryflask.views.MethodView - A class-based view that dispatches request methods to the corresponding class methods. For example, if you implement a get method, it will be used to handle GET requests.jinja2.BaseLoaderflask.templating.DispatchingJinjaLoader - A loader that looks for templates in the application and all the blueprint folders.jinja2.Environmentflask.templating.Environment - Works like a regular Jinja2 environment but has some additional knowledge of how Flask's blueprint works so that it can prepend the name of the blueprint to referenced templates if necessary.json.JSONDecoderflask.json.JSONDecoder - The default JSON decoder.json.JSONEncoderflask.json.JSONEncoder - The default JSON encoder. Handles extra types compared to the built-in json.JSONEncoder.KeyErrorflask.debughelpers.DebugFilesKeyError - Raised from request.files during debugging. The idea is that it can provide a better error message than just a generic KeyError/BadRequest.typeflask.views.MethodViewType - Metaclass for MethodView that determines what methods the view defines.typing_extensions.Protocol[GenericException]flask.typing.ErrorHandlerCallable - UndocumentedUnicodeErrorflask.debughelpers.UnexpectedUnicodeError - Raised in places where we want some better error reporting for unexpected unicode or binary data.werkzeug.datastructures.CallbackDictflask.sessions.SecureCookieSession - Base class for sessions based on signed cookies.flask.sessions.NullSession - Class used to generate nicer error messages if sessions are not available. Will still allow read-only access to the empty session but fail on setting.werkzeug.test.Clientflask.testing.FlaskClient - No summarywerkzeug.test.EnvironBuilderflask.testing.EnvironBuilder - An ~werkzeug.test.EnvironBuilder, that takes defaults from the application.werkzeug.utils.cached_propertyflask.helpers.locked_cached_property - A property that is only evaluated once. Like werkzeug.utils.cached_property except access uses a lock for thread safety.werkzeug.wrappers.Requestflask.wrappers.Request - The request object used by default in Flask. Remembers the matched endpoint and view arguments.werkzeug.wrappers.Responseflask.wrappers.Response - No summary
