react setState

Comment

incrementCount() {
  // Note: this will *not* work as intended.
  this.setState({count: this.state.count + 1});
}

handleSomething() {
  // Let's say `this.state.count` starts at 0.
  this.incrementCount();
  this.incrementCount();
  this.incrementCount();
  // When React re-renders the component, `this.state.count` will be 1, but you expected 3.

  // This is because `incrementCount()` function above reads from `this.state.count`,
  // but React doesn't update `this.state.count` until the component is re-rendered.
  // So `incrementCount()` ends up reading `this.state.count` as 0 every time, and sets it to 1.

  // The fix is described below!

Comment

@protected
void setState(VoidCallback fn) {
  if (_scopeKey.currentState != null) {
    _scopeKey.currentState!._routeSetState(fn);
  } else {
    // The route isn't currently visible, so we don't have to call its setState
    // method, but we do still need to call the fn callback, otherwise the state
    // in the route won't be updated!
    fn();
