Example 1 with DartNewExpression

use of com.jetbrains.lang.dart.psi.DartNewExpression in project intellij-plugins by JetBrains.

the class DartServerCompletionContributor method beforeCompletion.

            // implementation looks for the reference at caret and on Tab replaces the whole reference.
            // angular_analyzer_plugin provides angular-specific completion inside Dart string literals. Without the following hack Tab replaces
            // too much useful text. This hack is not ideal though as it may leave a piece of tail not replaced.
            // TODO: use replacementLength received from the server
            context.setReplacementOffset(context.getReplacementOffset());
        }
