enforce valid .sync modifier on v-bind directives

🚫 This rule was deprecated.
⚙️ This rule is included in all of "plugin:vue/vue2-essential", *.configs["flat/vue2-essential"], "plugin:vue/vue2-strongly-recommended", *.configs["flat/vue2-strongly-recommended"], "plugin:vue/vue2-recommended" and *.configs["flat/vue2-recommended"].

This rule checks whether every .sync modifier on v-bind directives is valid.

📖 Rule Details

This rule reports .sync modifier on v-bind directives in the following cases:

The .sync modifier does not have the attribute value which is valid as LHS. E.g. <MyComponent v-bind:aaa.sync="foo() + bar()" />, <MyComponent v-bind:aaa.sync="a?.b" />
The .sync modifier has potential null object property access. E.g. <MyComponent v-bind:aaa.sync="(a?.b).c" />
The .sync modifier is on non Vue-components. E.g. <input v-bind:aaa.sync="foo"></div>
The .sync modifier's reference is iteration variables. E.g. <div v-for="x in list"><MyComponent v-bind:aaa.sync="x" /></div>

Note

This rule does not check syntax errors in directives because it's checked by vue/no-parsing-error rule.

Nothing.
