Pub Version

Lint rules to warn you about common misuse of Grab and fix it quickly.

This package is incompatible with grab 1.0.0-dev.1 and above.
grab_lints is no longer necessary to avoid misuse related to the limitations that existed in older versions of grab.

Errors

Rule Fix Details
missing_grab_mixin ✅ A necessary Grab mixin is missing in the with clause.
wrong_grab_mixin ✅ The widget class has a mismatching Grab mixin in the with clause.

Warnings

Rule Fix Details
unnecessary_grab_mixin ✅ An unnecessary Grab mixin is in the with clause.
maybe_wrong_build_context_for_grab (✅) The BuildContext passed to the grab method has either of the following issues:
  • Not the one from the build method
  • Passed via a variable
The BuildContext parameter itself of the build method should be directly used to avoid misuse or confusion.

Quick fix is available only when an automatic fix is possible.
avoid_grab_outside_build A grab method has been used outside the build method of a widget.

It is discouraged although using the method outside the build method is possible as long as the correct BuildContext is used. Such usage easily leads to misuse or confusion.
