When I run this code Null check operator is used on a null value my flutter 3.0 please help me with what I do

CodePudding user response：

Flutter uses Dart language. Please refer to Dart - Null Aware Operators.

Add this

_featuredNews.title ?? ""

_featuredNews.imageUrl ?? ""

CodePudding user response：

Maybe _featuredNews.imageUrl! or _featuredNews.title! is the reason.

What about you try

1. use errorBuilder in Image.network
2. or change to like _featuredNews.title ?? '' to handle
3. or receive the variables by 'required' variables . . .
