Migration Guide

v2.0.0#

Removed the DualSignalBuilder and TripleSignalBuilder classes, and refactor the SignalBuilder class.

v1.x.x:

SignalBuilder(
  signal: counter,
  builder: (context, value, child) {
    return Text('$value');
  },
),

v2.x.x:

SignalBuilder(
  builder: (context, child) {
    return Text('${counter.value}');
  },
),

The new SignalBuilder is more powerful because it tracks any number of signals used in the builder method.

The context.observe method now needs T to be a SignalBase.

v1.x.x:

final counter = context.observe<int>();

v2.x.x:

final counter = context.observe<Signal<int>>().value;

ResourceBuilder has been removed in favor of SignalBuilder.

v1.x.x:

ResourceBuilder(
  resource: user,
  builder: (context, userState) {
    return userState.on(
      ready: (data) { ... },
      error: (error, stackTrace) { ... },
      loading: () { ... },
    );
  },
),

v2.x.x:

SignalBuilder(
  builder: (context, child) {
    return user.state.on(
      ready: (data) { ... },
      error: (error, stackTrace) { ... },
      loading: () { ... },
    );
  },
),
